Cobra Anchors _ Walldriller PLUS installation guide

[@cfrey10]

Great product Cobra - I was a little worried about the idea of not predrilling but gave it a shot and it worked like a charm. Didn’t notice the drill bit that was included until after I’d already used a screw driver, but no biggie. Thanks guys.

[@jle4652]

I recently bought a pack of Walldriller Plus (with #10 gauge screws with a stated weight limit of up to 175 lbs. on a drywall) A plastic anchor that supports 175 lbs.? I was curious and decided to give it a try. So I tested them on a piece of sample drywall I use for testing new fasteners. Sadly, none of the Walldriller plus worked. The blue part didn't even open up when I tightened the screws all the way in. This was disappointing because I like other Cobra products such as TripleGrip plastic anchors.

[@niko9942]

Just bought a case of these for $20. Installed according to the instructions. Some prematurely engaged the blue part and cracked when installing the screw. Others cracked when installing the plastic piece. Tried 6 very carefully and they all broke. Trash IMH. I'm returning them today.

[@jimblum6931]

My experience too - this product is shit!

[@jimmyyounger618]

Same. I'm pissed that I had to spend the gas money to travel from a rural area back to the store just to get something other than brittle, break-on-every-try junk.

[@nedflanders1559]

Just used 4 if these to hang a stainless steel backsplash behind a stove. Worked perfectly!

[@jerryenoch5267]

These looked great, but they aren't. In drilling 5 holes, the anchors failed twice, requiring me to fill large holes and finding another place to mount. I will try to return them.

[@davidkidd2961]

I had the exact same issue and experience as other professionals here, (yes I am a pro). I too have used other anchors of similar type. I like the CONCEPT as illustrated in your CGI video above, but in real world application it just doesn't work. I challenge you to post real world videos of your "extensive testing" in which "this issue has not occurred"!

[@918scott4]

The blue legs do not spread. I can crank on the screw until it is stripped and they hardly ever work.

[@johnd9357]

I wonder if they changed something? I just installed 12 of these and every one of them worked just fine?

[@TheBlackSheepChronicles]

@@918scott4 same here - just tried these yesterday and stripped out before I could screw through the drywall- then you cant get screw out - these suck so far - now that I see others have the same problem - on to another system ughhh (terrible instructions as well on the box)

[@PaulHembery-k5x]

Agree with other comments, these are not great. The theory is wonderful. But even with a pre drill, when screwing in the plug, the blue pieces expanded and the plug sheared off. What can I do now? I have half a plug in the wall. The concept is ok, but too many others have had the same experience.

[@terrywittek3496]

I want to use your anchors but not the screws. Can I use the screws from the shelf kit? Thank you.

[@lg4360]

Just tried using them to hang some cabinets. Bought the 205 lb weight anchor. The anchor screwed into the wall easily enough, but screwing in the screw turned the anchor. The blue part is supposed to expand and hold the anchor. It did nothing. Returning to the store. I used a good old fashioned toggle bolt anchor and had zero issues.

[@918scott4]

Yep, happens to me all the time then I have to move the anchor, patch the huge hole, wait to dry, sand then paint. Big waste of time.

[@MtPockets14U]

As a contractor I'm not happy with these either, same issues with spinning, and not being able to back of the fasteners screws without entire anchor spinning. Sure would be nice to find a real world application video on others using this product.. maybe it's possible I'm doing something wrong when it comes to this style Anchor.. been using the other style for 20 years.. no issues..

We are sorry to read this. We can assure you that we have intensively tested the products before putting it on the market. We will evaluate the relevance of making a video of the real application testing. However, we would like to inform you that we have adjusted the installation guide to add the following: Once the screw is flush with the object surface, continue tightening 3 to 4 complete turns. In order to expand the legs, it is important to use the right anchor with the right drywall. Anchors #6 and #8 will work in 3/8'' and 1/2'' drywall. Anchors #10 and #12 will work in 1/2'' and 5/8'' drywall. Installation instructions: 5. Using a screwdriver, push the tip of the WallDriller PLUS into the drywall in a screwing motion. 6. Turn clockwise until flush with surface and firmly in place. 7. Insert the screw through the object you need to affix and turn clockwise until the head of the screw is flush with the object surface. 8. IMPORTANT: To activate expansion of the legs, continue tightening 3 to 4 complete turns.4

does the right angle doohickey come in the package?

[@jimmyyounger618]

@@cobraanchors2476 What's the shelf life of your junk? The ones I got can't even make it into a substantial pilot hole, (that I supposedly don't even need to drill), before simply snapping off like 50 year old sun-baked plastic being worked in sub freezing temps. I'm curious to know if you used different material and/or manufacturing contractors who made sub-spec substitutions. I'm not the only one pissed who returned these. The guys in Menard's hardware wish they could quit putting them out because most of them get returned. People give them a hard time they don't deserve because Menard's stays with the poor choice of carrying rather than discontinuing these. The markup margins must be pretty damn good to continue selling a product with the expectation that some percentage of people will just throw them away rather than bother returning garbage products.

[@BoSecatero]

Why does it break and strip before it gets halfway in?

[@concreteangel2599]

When they work, they work great. When they don't work...more times than not...they f*ck sh*t up. Love how this video doesn't show the need to predrill even though they're box says it's needed. Even with predrilling they still break a lot in the wall.

[@ethanosborne9183]

If you have gotten these already and are watching this to see how to use them, stop. Go return them. It's not worth it. I ignored the other comments thinking I would be different. I'm not. Go return them and get something else. These do not work and you end up with 1/2 inch holes in your drywall that you'll now have to repair or hide behind whatever you were trying to hang up

[@Ski138]

Where can I get one of these screw bits sent to me? I double checked where I dumped my 40 pack of these anchors and do not have a bit for this. When I used a regular number 2 Phillips bit, it drove in 1/3 of the way and then tapped out and started stripping the anchor

[@cobraanchors2476]

WallDriller PLUS #6 and # 8 works with Philips bit #2, WallDriller PLUS # 10 works with Philips bit #3 and WallDriller PLUS #12 works with diver bit #4. Drive bit #4 is included in the WallDriller #12 packaging. Should you need driver bit #4, please send us your contact information to [e-mail] and we will send it to you.

[@stevenbarraco4853]

How do you know when to stop turning the screw. Should you keep turning the screw until it's tight. Does it ever get tight?

[@michaelwalker3920]

I believe the directions said when the screw is set against the bracket your mounting you turn 3-4 full turns to engage the blue wings fully. I’ve had no issues. I did break one initially but then I screwed them in slowly and steady and they went in perfectly. And I did drill a pilot hole which did seem to help.

[@lauramiller8665]

Help! My anchor wasn't going in well, so checked the video to make sure I was doing it right...I was. So I added a bit of pressure and the anchor broke! Half is in the wall. How do I get that out?

[@lauramiller8665]

Was able to get it out...whew! But I am leery of these. I am putting up a simple shelf for paperback books. This is the very first support hole I was doing. Will try again but the first anchor stopped turning, I think because the plastic was too big for the screwdriver. The second broke. I predrilled the hole so I know it is hollow.

[@lauramiller8665]

Tried it without predrilling...that is a joke. Taking these back. What a waste of my time and I have one humongous hole in the wall.

[@HowisonMontessori]

I bought a pack of 2 packs of 4, 205 lbs #12 filler plus. Is the weight per screw or does it require all 4 screws for the weight threshold of 205 lbs. I’m hanging a hammock and I’ll be using 2 packs. Does this equate to only 205 lbs, or does each pack (of 4) equal to 820 lbs. Thanks

[@cobraanchors2476]

4 anchors #12 will support 820lb IF and only if the fixture load is evenly distributed over the installed anchors. In addition, WallDriller PLUS loads are for static applications in gypsum. Hammock is a moving fixture. WallDriller PLUS is not the right product for this application. In order to guide you in choosing a safe anchoring option, we need more information regarding the material in which the hammock will be fixed.

[@kevincrockett8960]

Are these any good for mounting tv's? I intend to use 4 175lb walldriller plus on a fixed mount, 2 on one side going into a stud, 2 on the other side with no stud. TV weight is 75lb

[@johnd9357]

Wow. Reading the comments I must be an extreme outlier. I bought these to hang my Milwaukee packout system and I did almost 20 of these and had no issues at all. I screwed them in by hand without a pilot hole, and kept turning the screw 3 or 4 revolutions like the instructions say. You feel it get tight and gummy, but it’ll never lock up solid like running a bolt down on metal or something. They seem to be holding just fine for me. Didn’t have any issues with breaking or the fastener spinning in the wall. I came here expecting great reviews but got the opposite. I wonder why so many people are having issues? Makes me want to make a video showing real world use.

[@jimmyyounger618]

Have you made that video? I'm also thinking of making a real world video showing how one after another of these simply snap and break off despite anything I've tried, including drilling larger and larger pilot holes to try to prevent the weak, brittle plastic from failing. In my comment, (below), I mention how the sales associate hates these because most of the ones they sell get returned for this very reason. Count yourself blessed to have gotten some from a materials or manufacturing contractor who didn't substitute sub-spec garbage, if that's the explanation for your satisfaction.

[@emanuelvalentin1788]

These anchors won’t expand!! Help

[@cobraanchors2476]

In order to expand the legs, it is important to use the right anchor with the right drywall. Anchors #6 and #8 will work in 3/8'' and 1/2'' drywall. Anchors #10 and #12 will work in 1/2'' and 5/8'' drywall. Also, it is very IMPORTANT: once the screw is flush with the object surface to continue tightening 3 to 4 complete turns. Installation instructions: 1. Using a screwdriver, push the tip of the WallDriller PLUS into the drywall in a screwing motion. 2. Turn clockwise until flush with surface and firmly in place. 3. Insert the screw through the object you need to affix and turn clockwise until the head of the screw is flush with the object surface. IMPORTANT: To activate expansion of the legs, continue tightening 3 to 4 complete turns.

Good concept, poor execution. Tried and they would not engage at all. Just kept spinning as I added the screw.

If you’re having trouble with these you probably should stay away from tools and home improvement all together. Super easy to use, with a little bit of pressure they went right in. Thanks @cobra anchors.

[@shizzyeaglefeather3407]

Picked these up garbage please do not waste you money on these easy snapping pieces.

[@lonniefowler9613]

I just tried these the first time. I followed the instructions to a T - according to the package and this video. I wish I had read the comments first. Every anchor failed, didn't engage the blue part, and now I'm left with 4 large holes in my drywall I must now patch and paint. The failure rate seems to be a major disconnect between their R&D department and the real world. Stay away from this product.

[@tburrrg2502]

Absolute garbage. Listen to the pros and contractors here: these are absolute shit and attempting to use them is a gamble that may cost you with a giant hole in your wall.

[@jimmyyounger618]

Easily one of the worst products I've ever been ripped off for. Try after try - even increasing the pilot hole size for something that supposedly doesn't need a pilot hole. Snap! Snap! Snap! One after another and all they do is break off. I bought mine off the shelf in Menard's and returned to the hardware section to see if I could tell if I got old, brittle stock or something. "Doesn't appear so," says the sales associate. "I wish we'd quit selling these because returns of the unopened ones are a chore." This crap is infuriating when you live in a rural area and the fuel to return junk and buy something that works cost more than the product.

uselss for a novice

[@cobraanchors2476]

We are sorry to hear that. Cobra is trying to give as much as possible detailed installation instruction via video and installation guide. Here are the detailed step-by-step instructions. 1. Using a screwdriver, push the tip of the WallDriller Plus® into the drywall in a screwing motion. 2. Turn clockwise until flush with surface and firmly in place. 3. Insert the screw through the object you need to affix and turn clockwise until the head of the screw is flush with the object surface. Continue tightening (one to two more rounds) to activate expansion mechanism until firmly in place. Note: DO NOT USE FOR MOUNTING TELEVISIONS.
