Concrete anchors

Concrete anchors are a heavy duty anchor for fixing objects to masonry surfaces. Here we use a thru bolt to demonstrate how to fix a piece of wood to a concrete slab. One problem with thru bolts is that they are extremely difficult to remove and so here we have drilled the hole much deeper so that the old thru bolt can be knocked into the hole.

Every time I have a DIY job to do, I come to your channel and there's a video there waiting for me. This morning I had no idea what an anchor bolt was, now I know how to fix my fence post to concrete. Please keep these videos coming, they're a goldmine of information. Thanks again.

[@chanlapming]

I had a few questions on using these before starting work on a deck frame. All questions answered. Cheers fella!

[@VFEA20]

Best video about anchor bolts. I've been looking at several and yours is the only that explains its use and removal. Thank you.

[@ultimatehandyman]

You are welcome. Thanks for the comment

[@NoFaithNoFear]

Good idea about using rustproof bolts. I wasn't sure whether the bolt would split the brick as it expanded, so you've put my mind at rest. The timber is 2" thick which is about 50mm, so I'll look for bolts which are around 120mm. Thanks again for your help, much appreciated.

Probably one the best videos on this I've seen. Great job!

[@ultimatehandyman]

Thanks for the comment

[@redmanmr2]

Your easily pleased

[@ultimatehandyman]

+Efstathius Placidas I don't think so, although you can use Rawl bolts etc. which leave a threaded female insert in the hole, which you can then bolt to.

[@pnywse77]

Thanks for taking the time to post this video, it was a great help.

[@halseyballistic]

Outstanding explanation. Thank you for your time to post this video for us all to learn!

Great video, concise and spot on. Thanks for the information.

[@staffy4389]

Brilliant, thanks. I'm not a handyman, so this is very helpful. Hanging a heavy side gate soon and now I have a good idea how to do it. Thanks 👍

[@ultimatehandyman]

I'm glad the video helped Thanks for the comment 👍

[@Bwanar1]

Don't forget to blow out your holes. A lot of times trash can get in the way of driving the bolts to the depth you want and you can't remove them to do it later!

[@nounoukos]

Most useful advise here guys.

[@philhode5104]

Yes important to blow your holes clean

[@ArcticVulpes]

Thanks for taking the time to demo this.

[@ultimatehandyman]

You are welcome. Thanks for the comment ;-)

[@littlepiaf]

"UH", thank you for taking the time to make these videos. I love them! Can you use this same technique in a vertical stone wall? I want to fix something to my limestone house.

[@wardl895]

Thank you very much for the description and example... Rich

[@camvec]

great vid - quality little tip about an extra 1" in the hole, I'm away to use some of these to fit a hanging sign iron bracket to a wall. thanks again!!!!

[@pinewomble]

Thanks for the reply - will look further into it - good stuff!

[@harperjr3]

[@howlingc5952]

Great video. Excellent tip to drill the depth out more than needed for an easy solution if you want to remove the bolt. Well done. Cheers and thanks.

[@ultimatehandyman]

You are welcome. Thank you for the comment ;-)

[@andyh5950]

Ultimate Handyman look at Greg German on KZbin for how to remove through bolt's from rock!

[@cyvirus5041]

Thanks for the video, now I can go back and fix the loose wall my contractor should of fixed. He replaced all the wood in the wall but didn't anchor it to the foundation. Thanks again

You are welcome Thanks for the comment

[@rengamz]

thanks for getting back!

[@goingcrazy4u1]

Great tip. Thanks for sharing.

[@nathenpeter7]

Thanks. It is smart to keep the hole deeper so you can drive the anchor down into the hole later if you want to so it doesn't harm anyone for the rest of its life.

[@ultimatehandyman]

Thanks for the comment ;-)

[@reygm3639]

Or just grind it 😂

[@scalephrase]

Excellent! I just used 3 wedge anchors yesterday (3/8" x 3 3/4") to install a 2"x4"x8' pressure treated sole plate. Two of them were perfect, but the third anchor was inordinately tight. I see now what I did wrong: I did NOT drill a "wide enough" third hole (for the third anchor) in the piece of lumber--to give the bolt some slight "play." That is, the hole in the lumber did not line up perfectly "plumb" with the hole in the concrete, causing a slight "binding" of the bolt. Thanks for posting this fine video. You solved my problem!

[@ultimatehandyman]

👍

[@NotLegato]

oh, thanks! if i hadn't seen this, i would've probably tried to eventually remove them by trying to saw them off, which would've taken AGES. well this was straight-forward!

[@ibabkodal]

Wonderful! Thank you sooo much you video very very helpfull... 😊☕

[@mang1953]

Brilliant mate ! good old fashion common sense being used here.... nobody seems to think ahead like you have sir. The "what happens after" I no longer need this anchor in it's current location? simple ! it's a dur-moment.... just, allow enough depth on the [pilot] hole during the original install, to address any future safety concerns. Well done & very useful. cheers

[@Ike92]

Thank´s man, it was very useful. Regards from Colombia

[@Spawned-in60]

This is exactly what I needed. I am going to secure a costco gazebo to an exposed aggregate concr deck, and hopefully keep it from blowing away. Thanks man.

[@ultimatehandyman]

+John Bullock You are welcome.Thanks for the comment ;-)

[@ianbrooks3091]

Excellent video. I'm building a timber mono-pitch outbuilding/shed and looking for a suitable fixing to bolt/screw the timber frame walls to the base. Obviously these are around the edges of the concrete base so are close to the edge. My question is - how close is too close - the timber frame is made using 3"x2" (the 3" dimension is the width of the frame) so is this too close for this type of fixing? What would you recommend?

[@welcom688]

the job itself isn't particularly difficult but it doesn't prevent it from being a great tutorial video! I watch it through and find it very useful and enjoyable( nice and clean, no talking shit). Thanks for sharing with us!

[@DavidTermini]

Thank you for the information. I have to anchor to concrete to attach metal cable between two walls to hang lights. Do they make anchors for this purpose? Thanks,Dave,Frederick Maryland.

[@donmark144]

Perfect. I always thought that the hole had to match the length exactly. That is a great tip.

[@jigglestumps]

That's brilliant, thanks for the quick advice. I'm installing it today so I'm glad I asked. The Resin video was really helpful as well. Just one question. When I move house will I need to angle grind the end so it's flush to the wall and then fill it or is there another way, like in this video, where I can tap it in? Thanks again. Very helpful. J

[@daskeleng]

Useful video. Thank you so much. Now I have a better idea of what I got to do for my home project. Thumb up to you

thanks mate, i will use this to bolt my safe to the concrete floor in my closet.

[@glenchaplin288]

Great video, thanks for info and tips. I want to use a couple of these to affix a timber post (for hanging a gate off) to the end of a breeze block wall. How far from the end of the wall do you think I'd be safe fitting these (to avoid cracking the breeze blocks)?

[@msdanaryan]

THANK YOU!! I'm going to try it. 😬 Wish me luck. I need to secure a polycarbonate sheet over a basement window that's broken. Hoping this works.

[@ultimatehandyman]

+MsDanaRyan ツ Good luck with it ;-)

[@mrdavidurquhart]

I find the bolt goes in a tiny bit easier and grips slightly better if dust is blown out of the hole. A short length of flexible tube can be used to blow dust out of the hole before the bolt is inserted. Finally, as shown in the video - there's no need to over tighten these bolts. If you do you risk pulling the bulb-end of the bolt through the jacket - and then the bolt and hole are useless. Thanks for yet another great video!

[@drdzdd]

That's a great comment, thanks

[@Jason52597]

Great video

[@boblozaintherealworld3577]

This is a cool video. Good basic info on the anchor bolt (thru-bolt as the English gentleman says) which, in my business (architectural graphics) is the most used and most unseen of hardware. I'll be passing it on.

ty so much my friend, needed to here, so i could learn

[@ultimatehandyman]

You are welcome Thanks for the comment ;-)

[@johngo6283]

Very nice video. One suggestion: Use a shop vacuum to remove concrete dust from the hole.

[@ultimatehandyman]

+johngo6283 Thanks for the comment ;-)

[@joemonroe9456]

stick a small tube into the vacuum hose so that you can go deep into the hole.

[@justjustjoo]

Argument: That would be 100% waste of time. I'd say that the anchor holds just the same weight if you vacuum the dust or not.

[@heroknaderi]

I enjoyed watching your video also another name of that anchor is sleave anchor I used these all the time because they can hold tons of weight. I used them one time for fastening garage door tracks to concrete walls🤩😎👍

[@pinewomble]

Thanks for the quick reply :: In regards to concrete screws --- The structure is a basic carport, using 50mmx50mm / 75x75 timber posts: The fixings I'm using are square post supports, a hole for an m8 on each corner - do you think a concrete screw in each corner would hold well enough to support the posts? (2.4m max height, opposite side fixed along wall with a horizontal timber support) Thanks - Martin

I'm getting ready to build a new wooden front porch. I needed to know how to bolt 2 posts to the brick wall. I'm going to use this method. Thanks!

[@ultimatehandyman]

***** You are welcome, thanks for the comment

[@michaelm3052]

***** Well, I'm done with the porch and I'm getting all kinds of compliments. The 2 posts against the brick wall are more solid than I ever imagined they'd be. Those bolts were a lifesaver.

[@ultimatehandyman]

***** Good stuff ;-) Thanks for the comment

[@voodoomotion5855]

Great tutorial!! I'm planning to add some joists above the ceiling rafters in the loft to make a storage room, would you recommend these for attaching a wallplate to a stone wall? Thanks

[@ultimatehandyman]

Someone once said that these are only suitable for concrete, although I'm sure the ones I have bought in the past just said "masonry" on the packet, so it's best to check with the manufacturer. If you go to the makers website, it should tell you what substrates they can be used in. Thanks for the comment

[@jdbucha]

Great. I'll use this to anchor a safe in my garage.

hi pal those helicoils worked perfect !!the moped man rides again 😃😃😃😃😃thank youuùuu!!!!

[@funkymonkey1198]

Excellent video, thank you. I ordered some tricep dip bars from Amazon and it came with 4 of these per arm. Are they suitable for fixing to a solid internal wall, please? It is plastered but it is a 1970s house so behind the plaster is solid heavy blocks. Thanks.

[@ultimatehandyman]

+Nachatar Dhaliwal They are supposed to be used in concrete only, but I have used them in most solid blocks with no problems yet, so they should be ok ;-)

[@scottmclean4237]

hy can these b used to attach wall brackets into brick? I am using a length of unistrut to brace against my back garden gate to make a solid secure retractable bar lock. the unistrut will slide in and out through the bracket.

Thanks Great point about drilling deeper I didn't do that on a wall for bike rack Now they're sticking out

[@ultimatehandyman]

Glad to help 👍

[@pinewomble]

Hi - a quick question regards to not using thru bolts 'near the edge of concrete' as you stated in your video --- what's a minimum safe distance from the edge? I was thinking 3" would be ok, but would rather ask the expert...

[@eddiefoy3701]

If its in a floor, I *always* drill straight trough. If the anchor gets screwed up (buggered threads, spins in the hole, etc.) you can pound it down and install a new one on top of it. Hitting rebar is always fun:)

[@ultimatehandyman]

Thanks for the comment

[@racerx1121]

Hopefully you still monitor these questions! I am trying to mount a ledger board on a cinder block wall, so the anchor bolts will fall into the cavity behind the holes I drilled. Also - the expanding flange doesn't expand. perhaps the cinder block hole is slightly too big or the cinder block material is too easily broken away inside the hole making it too loose?

[@ultimatehandyman]

Hi, I am not familiar with cinder blocks I'm afraid (we don't use them in the UK). I'm not sure what people use when fixing into cinder blocks, perhaps resin would be a better option- kzbin.info/www/bejne/pYatgZ2AqMmfZsU

Nice video can these be used in brick?

[@ultimatehandyman]

They are only to be used in concrete, according to some people. But I have used them in brick in the past and they worked fine, but resin fixings might be a better option- kzbin.info/www/bejne/pYatgZ2AqMmfZsU

[@tigertruckerman]

I am a bit on the thick side,do you mean place frame on top of sill,and drill straight through both,if so they would be hard to stop moving.

LOL Thanks for the comment

[@clarkeugene5727]

Now that's, worth a few chuckles at least! The drilling was a Bit useful also.

[@coolvid]

If I needed the bolts to be totally removed and not pushed in to be covered, how would one go about that?

[@tomthompson7400]

great video , but , if you can brush the dust etc out of the way with the drill bit still in the hole , saves all the dust going in the hole . great tip about the full depth hole plus a wee bit for knocking the bolt flush later.

[@ultimatehandyman]

Thanks for the comment 👍

[@wulbert2001]

whats the best screw to use for fixing a 3 by 2 onto a concrete wall to fix a gate onto it.

[@centremanagers9965]

Could I use these in sandstone or is there something more suitable? It's to fix bolt down brackets for fence posts on a low wall.
