You ground off the zinc coating on the bolts meaning you were just testing steel on steel bonding. Zinc metal is much too soft to make a bolt from and many metal parts you find at the hardware store are zinc coated to prevent rust like your original angle bracket. I really appreciate your channel and am only trying to help, not criticize.

Fuck me I know I'm getting old when I actually searched for this video, I'm going to play on my switch now to balance it out!

[unknowncrash]

holy crap, this experiment is amazing!!!

Legend says whatever he touches turns into 363

The pull strength is very high, but the sheer strength will be very low. Do another test and apply a shearing force to the two bolts. The bolts will break apart. I've tried super gluing metal pieces together, and while the bond seems to be very strong, if you apply a lateral sheering force to the two parts, the joint will EASILY break apart. That's because the surfaces of the two metal parts are relatively smooth, and the only structure holding against a sheering force at the joint is the actual breaking strength of the polymerized cyanoacrylate glue, which is a fairly weak plastic

That's impressive. Can you redo the test with a smaller interface between the metal parts? That way you can cause them to fail at values that you can measure with that setup.

[dreamationkhraw]

If the bolt gets hot, will the bond came out?

[davidgamer]

How does this test work exactly? Like wouldnt you measure the glue weight up until it breaks? Idk if I looked wrong but I didnt see any of the vonds break at all, meaning it definitely couldve taken more weight right? Especially since 300 pounds is like a tenth of what the steel to steel glue strength is rated with those bolts that were at least 1 square inch....

[chaplainmattsanders]

Impressive is the word. Wow! Good vid. Thnx.

[malikalik]

Bro, you need to maintain at least an hour of continuous tension to decisively measure its tensile strength.

[DennisMathias]

HOLD IT! You have to carry that weight for like an hour. Just doing a quick lift is inaccurate.

[barrycole]

To findcout the full strength, of different metals you should sustain a weight like you've done, but then pull to destruction. The drop of glue is the same, but wider on washer head, and type of steel might make some difference.

Having tried this experiment but I no one thing This is some strong GLUE. Gorilla glue ain't got nothing on this.. thanks Gulf coast Monticello fla. See y'all soon.

[zmaxx]

Uh, I think it says it works on metals on the package since the 70’s son.

[somerandomguyfromtheintern]

mmm, this was a pretty bad test, equipment was not up to snuff.

[rube]

You proved absolutely nothing. All testing for glue is done to the point of shear which you did not do
