Love these video's. I'm a retired maintenance mechanic myself and I save all my bolts and sort them into cans for later use. Having seen so many bolts in my life I can identify a bolt pretty quickly (metric excluded) but the strength sometimes is difficult if they use alternate markings not commonly used. I commented in one of your other video's I've been researching bolt head sizes (which in my opinion would make a great companion video to this video) and why metric bolts vary so much between JIS, DIN and ISO. They seem to get along with their 4mm 5mm and 6mm bolts but all go their own way from there on. For instance JIS uses a 12 MM wrench on a 8mm bolt and ISO and DIN use a 13 mm wrench. And on a 10 mm bolt JIS uses a 14 mm wrench and DIN uses a 17mm wrench and ISO uses a 15 or 16 mm wrench. And on a 12 mm bolt none are the same ranging from 17mm 18mm and 19mm wrenches. And DIN is the only standard that makes a 7mm bolt and uses an 11mm wrench. And ISO (at times) is the only one that uses a 15mm wrench on a 10mm bolt. I wish these people would standardize the head sizes so we do away with these extra wrench sizes.
First, I really appreciate your enjoyment of these videos. I have fun with it, but they do take time, so nice to know people benefit/enjoy! The other element I really enjoy is all the comments and conversation. I have been learning a lot (nobody knows everything); I'm a perpetual learner. To your example, I was mo unaware than I should have been regarding the various standards regulating metric bolts. You're exactly right, the head sizes vary and many around the world really don't know that....simply because they're not exposure to all the variations. I definitely have your suggestion on the list! Thanks for stopping back, and see you at the next video!
Great info! I tend to reference the McMaster-Carr “specifications met” information pane for the rundown on different standards but this was a great in-depth explanation surrounding the JIS. Keep up the great work!
Thanks for the comment. I haven't used McMaster in the past, but I'll definitely check it out! Appreciate you watching and stopping back, I'm having fun doing it, and learning so much myself.
Do you happen to have a link to one with these 4, 5, 6, 7 marked bolts? I struggled so many times to find anything. And, in particular, why the seem to be fairly uncommon (at least in my part of the world and seemingly much of the world). At least now I'm familiar. Thanks for watching and sharing.

Just search bolt tensile strength chart👍
