The measured results
Every number below is read straight from the test. Scroll sideways to see all measurements. Products are listed in the order they finished.
| Product | Downward force test | Bonding quality | Twisting torque test | Torque failure mode | Failure mode |
|---|---|---|---|---|---|
| 1JB Weld Original | up to 15 lbs now now 17 1/2 lb okay we're up to 20 lbs okay 22 and a half lb okay up next is 25 pound | JB Weld won this competition and what's interesting about the JB Weld as you can see it stuck very well to the material | JB well just failed at 185 inch lbs | the JB Weld is just a little bit more pliable or a little bit more flexible | not tested |
| 2Devcon Plastic Steel | not tested | Devcon a lot like JB well did a terrific job of sticking to both the bolt as well as the steel... the epoxy is breaking free from itself and not breaking free from the steel | Devcon proved to be a little bit stronger [than JB Weld Original] | not tested | Devcon on the other hand is just very very brittle, it's a very hard plastic |
| 3Gorilla Epoxy | not tested | gorilla actually did a better job than I thought it would for a quick drying epoxy... as you can see though it did not stick to the steel it broke free | not tested | not tested | not tested |
| 4Loctite | not tested | I can't really tell much of a difference between Loctite and the JB quick weld, both of them did the exact same thing, they just didn't stick to the steel | not tested | not tested | not tested |
| 5JB Weld KwikWeld | the JB quick weld just failed 122 lbs | these quick epoxies just seem to fail at sticking to whatever surface you're trying to make it stick to | JB quick weld failed at 100 inbs | not tested | not tested |
| 6JB Weld Extreme Heat | that didn't hold at all, that's extremely weak, I got right at 10 lb | it doesn't appear that the extreme heat has very good adhesive properties, this stuff [is] very hard and brittle... it just sort of breaks away | it just failed just broke, I didn't even get 5 in lbs of torque | not tested | not tested |
How it was tested
- downward/gravitational force weight test to failure
- twisting torque test to failure measured in inch-pounds
- shock/impact drop test on the remaining strongest epoxies
- surface bonding and adhesion quality inspection
