Honestly, I hope your channel gets big

[@I_leave_mean_comments]

I think it will.

[@TravisTerrell]

I wish he was still making videos. His primers are absolutely top-notch.

[@mainesail3097]

First time watching this channel--This fellow is REALLY GOOD.

[@OMARYassin1]

Thaaaaaanks a lot 😍😍😍 you are very underrated for your efforts

[@foxpup]

Great video! When I was first learning about screw threads I started out NOT assuming there was only one helix but apparently there is always only one helix, at least for main-stream regular screws/bolts/rods. I would expect that single helix is almost always better and that's why it is that is why you vertually never see anything else. :-)

[@moeshouse575]

when i was a machinist i found out . that thrds 3 in and up was in a range with no standards. you just made them to fit. the fittings that was there.

[@miguelvega9263]

That foam roller screw is a such a good instructional tool. Well done!

[@believingdaydreams]

That was amazing.

[@rossg9363]

Screw this I'm going nuts 😉🤣

[@oxtoolco]

Nicely done. Makes me want to go out in the shop and thread something. Keep up the great videos. Best, Tom

[@larsvbundli1740]

We all mean like to "thread" something. :D

[@thebearjm]

I honestly think the metric system is way easier than the standard

[@RollingEasy]

The thing to do with Metric and Imperial is to learn them equally as in using your left and right hands and to use them both together all the time. When you do that, they blend together easily. A calculator and 39.37 is all that's needed as help.

[@user-zq6pj5jo8j]

So does the rest of the world..:)

[@monad_tcp]

@@RollingEasy I guess you have a point, as an computing engineer, I can either do arithmetic in hexadecimal or decimal or binary, it doesn't matter, I prefer hex, its easier because in computers everything comes in powers of 2 (because, binary). I can change bases or units, just don't mix them in the same piece.

[@patrioticwhitemail9119]

Commies. Y'all dummy's that can't count without your fingers. WE USE FRACTIONS! Our inch is based off something real: a seed. Our acre is based off how much land a animal can plow in a day. What's yours based off of? A stick some tyrant told you to use? One that can't be measured thanks to how protected it is in some museum? What? Next are you going to tell us to use a ten day calendar? Napoleon instituted it, but the church threw it in the garbage after he died because: #1 jesus, #2 fuck you, nobody used it, and I agree with them on both accounts. Y'all can keep your shit, and we will keep ours.

[@JM320STW]

@@patrioticwhitemail9119 the metric is based on the distance light travels during a certain amount of time, time that is controlled by the number of cycles a certain atom of Cesium

[@LadySoul4ever]

Yes, I learned something. Thanks!

[@kenzpenz]

Fantastic presentation, and all without an bunch of ahs, errs and long pauses. Keep em coming you guys are great. ..Thanks for sharing , Ken 79 year old retired guy, Marina CA

[@MikePeaceWoodturning]

Very well done video. I have hand chased wood threads on a lathe and use a threading jig to cut wood threads for boxes so found this interesting.

[@drbirtles]

Your channel is fantastic. Thanks from the UK.

[@NithinJune]

lmao most ikea stuff doesn't use screws

[@Hopeless_and_Forlorn]

Early in the training course for aircraft mechanics that I began in 1964, a month of shop time was devoted to hand tools, metrology, and hardware. The instructor was first class, and the projects very instructive. The lessons learned served me well throughout my career. But today I learned a few things from this video. What a great advantage these videos, and all of the internet, give to technical students today. Keep up the good work.

[@computhenics]

At first I thought how that long piece of sponge gonna help me understand it better? Then you wrapped it around the cylinder and I instantly clicked like. You are the best in this field.

[@tylerryan3280]

Hey man I just wanna tell you, I work as a house mechanic in a sugar factor in little old town. I'm glad I found your videos. There entertaining and I honestly learned something

[@howder1951]

Basic information, really well explained and very thorough . If I was an instructor, I would use this video for training you left very little room for questions, I applaud you.

[@arsenic1987]

Strange that when I searched for "multi start threads", this video was one of the top results... You should have mentioned that.. I'm just now figuring out what they are and could not for the life of me figure out why my trapezoidal nut didn't fit the screw with the exact same pitch and diameter.

[@LaneyMachineTech]

If I can get to it, I would really like to make a follow-up video on multiple start threads and different thread forms.

[@firzt0]

this honestly need more views. damnit you present the topic in a very interesting and concise way. love the cadence

[@FilterYT]

You're a very clear presenter, thanks for the videos!

[@kaarloleppajarvi6157]

Only 3 "banana republic" still use inch etc....

[@alessandroandrenacci2372]

All electronic printed circuit boards are worlwide bored in inches-pitches, and nobody can ( and neither want ), try a metric change . . . The world is full of machines producing computers, telephones, internal components and other usefull machines whose internal standard lenght is INCHE ( and its submultiple ). So "inches", more difficult to understand for we europeans, are so very important nowadays. Thank you to Adam who gives us a clear lesson on this topic ! ( Alessandro from Italy )

[@loboslobos14]

The nicest explanation you can find on KZbin. Please keep doing things like that.

[@BLONDpassionful]

I love this channel! - Mechanical Engineering student

[@BrilliantDesignOnline]

Totally learned some things. Knew a huge percentage of it, but you laid it out extra logical and covered all the major bases, so whether expert or neophyte, it was fun to learn or review. Thank you.

[@WhereisBrad]

Great video! Very helpful. About to purchase a caliper and pitch gauge so I can find the right screw for the job today, and for the rest of my life. Thanks so much!!

[@MA-kt8ly]

Screw this

[@alessandroandrenacci2372]

Adam, thanks for your clear lesson, inches are a bit hard for we europeans, newertheless they are so important, as you know all the electronics works on inches, bores on printed circuit boards are drilled at 1/10 or 1/20 inche-pitch . . . Even water pipes ( in Italy ) are sized and also threated in inches, even in a different mode, called here "GAS - inches" ( not WITHWORT ) . . . Before your lesson i didn't understand so much inches-threading , but now, with your help, all is so much easy . . . Thank you very much

[@Donna-cc1kt]

Can’t resist telling you this cuz you’re gonna laugh. I had a question and You Tube sent me your direction. Well, didn’t get my answer (yet) but I couldn’t stop watching. You are an excellent communicator and the subject was fascinating and understandable. Now for the humorous part - I’m a 71 yr old female that asked the question, - is more thread on a screw more secure? I’m holding two metal wood screws here and needed the one with the best hold. While one has less threads the “blade of the thread is sharper and appears slightly bigger. No worries, I’ll find the answer, I think, but thought you’d get a laugh from a older woman. Think I’ll be watching you again though!

[@lamonttblackshire1638]

You are amazing. This video was amazing. You are a natural educator. And you probably just saved my whole entire life! My superhero for today. Thank you for this video.

I'll never forget breaking a wrench with my brother taking a pedal off a bike....Then we clued in that it was left hand! We both came on to that wrench with all we had until it busted as we turned it the wrong way!

[@TheMudfly80]

I've watched a lot of educational videos and this is one of the best presentations I've seen, well done.

[@garbo8962]

We had a great old time mechanic who had to work on some old made in England machines. At that time believe England had their own thread standard before switching over to metric system. Old guy always called them bastard threads. Have used both SAE & metric boots & nuts & prefer the SAE.

[@carlosjoelgarcia3200]

Keep it up... Professionally done!! Understood foreign concepts easily.

[@gregpatey6355]

very well done and informative video... a bit of confusion that I have not been able to find the answer to yet... are SAE threads measured from peak to peak, from valley to valley or from peak to valley?.... I have a large bolt that when the threads are measured peak to peak, It would seem to have 4 threads per inch, but when measured at the valleys, I only get 3 threads per inch.... so would this be a 3tpi, 3.5tpi or a 4tpi bolt?... I would think the measurement should be started at a valley, and if it ends on a peak, this would be a full tooth count, but if the measurement ended in a valley, it would designate a half thread... in the case of my bolt, I believe it to be a 3.5tpi, but before setting up to cut one like it, I would like to know where to start... thanks

[@reaubhat]

I like the big foam bolt! Keep it up, Adam!

[@mrayco]

I learned something thanks

[@TheCondoInRedondo]

At the 5:33 mark, you call that a BOLT. Yet, earlier, you made the case that this would be a SCREW because it threads directly into a hole rather than being fastened by a nut. What am I missing?

[@Boudico]

One of the best, concise, explanations I've seen.

[@cortedemico]

at 4:42 i wonder if this math, or reality... i counted 21 'crowns'. one at he beginning and one at the end confuse me except through math. the first is zero, and not counted. in my mind i see the first as one... good to know the rules of engagement in this circumstance, though. should have visualized the 'zero thread' a bit for the less clever among us. ie: me

[@jimgourgoutis]

Fun fact: while most of the other fasteners on a bicycle are metric, the pedals are 9/16″ x 20.

[@Albanez39]

I don't know if their standard name is screw threads, but such threads are more commonly found on bolts. No matter if they go through a hole and are fastened with a die, or screw directly inside the hole. Here in Europe, screws are only the tapered (conic) things used with wood and concrete...

[@magnusklahr8190]

[@AquilesMelomtl]

Very well explained! Thanks from Montreal, Canada!

[@sopalen]

I am pretty sure both of them are screws, a bolt is cylinder shaped objekt with no threads (ribbit) on it. But if you add threads then it becomes a screw.

[@MrSaemichlaus]

Nut types are numerous. Hex nuts, lock nuts, flange nuts, T nuts and deez nuts.

[@aprilk141]

Awesome video, but if you had done metric instead you could have spent way less time making it.

[@saiteja5372]

Wow... really great video! Can you make a video on go gauge and no go gauge

[@k9wiREless]

so I’m confused, if you 500 thousands bolt has a thread pitch of (60°) this will calculate out a right angle triangle have a height of 0.043 and if the hole which you drill has allowing for threads, which would only be 0.414 thousands but, the thread chart specific 29/64 (0.453) that’s a difference, right…..what’s going on there

[@k9wiREless]

like am I losing out on 0.040 by following the thread chart, cause if that’s the case I’m gonna start threading those holes closer to the calculations for better tolerance

[@Ms-yn7qk]

Sir could explain effective diameter of thread

Hello, i have some question on the bolt part 1. How to judge how many nut can we put on the bolt? 2. How to judge the bolt should put on top surface or below surface?

[@davanillagorilla9210]

Shun Jian Lee it will have to be from drawing specifications to where it goes, and as for how many it can fit it depends on the length of the bolt and the thickness of the nut you're using
