Yes. No. Maybe.

Gentlemen, welcome back to the shop while we got the torq structomatic out, we're gon na put a little bet to rest. There are some interchangeabilities between the metric system and the standard inch imperial 15. 16 wrench, for instance, is the same as a 24 19 millimeter same as three carter. People argue with me, but heuristically.

That is experience based. I know they're the same 22 millimeter and 7 8 on hydraulic fittings same same. So what we're going to do, though, just to make sure, is we're going to run the box end of the 24 on this 15 16 across the flat bolts. This is an inch standard, bolt 5 8 national course, and we're going to see if she slips or damages the fastener in any way from the previous demonstration.

We know that this forester is yielding that is it's stretching out and it's gone beyond its strongest point. So it might fly out and give a summer teeth, but we want to see that the weak point is not the box end that the fastener is indeed yielding, and it's not the box end. That's slipping! I'm going to apply some hydraulic power. We'll give her a couple chooches, oh now, that is interesting, because that is on there good piece of oh.

We can see that the 24 is close enough to the 15 16 to do a fine job and not mar the fastener. Even in 12 point.

    Awesome video's. enjoy them alot 🙂 I was wondering if you would like to try a torque test with the open end of the wrench? Greets from the Netherlands

    But – BUT!! What does that have to do with my birthday – 02/22/52 and almost as important – twosday and 02/22/2022? Huh? Answer me that!!

    22mm and 7/8 are a bit too far apart but like you say 24mm and 15/16 also 19 and 3/4 and 16mm and 5/8 also 8mm and 5/16 and 27mm and 1-1/16…. ho and 14mm is a tight fit on 9/16 bit will go

    Amen! People who break out calculators and jabber on about deep decimal point differences aren't wrenching on anything anyhoo
    16mm = 5/8", 19mm = 3/4", 22mm = 7/8" 24mm = 15/16" Heck i use 9/16" in place of 14mm when I need to, arrest me!

    Retry the test with some 10 mm or 13 mm bolt's..i will bet you, that the bolt's head will become round as a clock..

    That happened to my Snap On Hammer also. They replaced it free. I think the plastic hardens and becomes brittle after 20 years.

  7. Avataaar/Circle Created with python_avatars Richard Anderson says:

    Fit? Some of them will….ish. 7/16- 11mm 9/16-14mm etc. Most of us have tried and decided that having the fastener stuck in the tool isn't worth it.

    I would say that the temperature sensing hammer made a return, but I'm thinking given the video subject matter it must have been an incompatible imperial hammer with a metric wrench.

    13mm and 1/2AF definitely, U.K. based 17 year old me driving a junk box in the early 90’s learned these things from engineering father…..
    The ones that don’t fit, you learn from lack of skin on the back of your knuckles when they slip….

    For working on rusty junk, I grab both metric and standard and use whatever fits the tightest. Then I grab my die grinder and cut it off because it was never coming off peacefully to start

    What do you mean, "metric" wrenches? Everyone knows there are 2 systems: imperial wrenches, and adjustable wrenches.

  12. Avataaar/Circle Created with python_avatars Thane Irwin says:

    Sure do. Work in Oil/Gas and Everything is of course imperial as it follows API standards. 5/8" Studs work with 27mm. 3/4" with 32mm and 7/8" with 36mm. Matches fairly close to structural fastner sizes in Metric.

  13. Avataaar/Circle Created with python_avatars Nebbia affaraccimiei says:

    I bet there are bigger tolerances between brands which are supposedly the same size than between a corresponding Metric/Sae

    I've got a few tools labeled 3/4" / 19mm..
    I've also repeatedly used a 13mm socket on some 1/2" nuts that holds a cover on a machine at work, just due to the fact that I don't own a 1/2" socket. sometimes the nuts get stuck in the socket but I'll always get them off and back on again…

  15. Avataaar/Circle Created with python_avatars Nicholas Slovacek says:

    A 24mm wrench is .1875mm larger than a 15/16 wrench. Usually not a problem to use a 24 mm on a 15/16 but occasionally find a annoyingly snug fit if you go the other way. A 19 is a little more sloppy but can do in a pinch if you don't have to much chooch in the gorilla doing the wielding.
