Flare nut wrench torque tests?

[Adam.C]

Can anybody say what the failure mode was? I see torque limits. Did the wrenches slip? Break? Keep in mind the wrenches are different lengths as well. The top rated wrenches appear to be short and fat.

Check the images from the German publication - it shows the failed end of the wrenches - bent, broken, etc.

Negative. Used Google translate. Snap on didn't bend. Form unverandert means "dimensionally unchanged". Not sure what the failure mode was.

I wasn't talking translation, I was talking actual photos.

The photos show bent wrenches, busted rings, etc.

If the Snap-on wrench didn't bend/break, then it didn't bend/break.

If a particular wrench didn't bend or break, but is considered a failure, it's a reasonable assumption that it slipped.

Come On Adam just go with it, Don't worry about the Details.

Based on the fact that a bunch of the wrenches had the exact same max value on the box end test, I suspect that number was the highest they could apply.

The snap-On wrenches reached the maximum of 240NM at the box end. The test machine could only test up to 250NM so they stopped at 240NM. The DIN norm for 13mm size is 107NM.

Like posted above the (most likely) strongest flare nut wrenches will be the Hazet "612N" series. 612 N-10 (10mm) /612 N-11 (11mm) ...

.... and the 612 N-8x9, 612 N-10x11, 612 N-11x13 and 612 N-12x14....:

So that looks up as about 177 ft. lbs. So Mr. T would have a sore hand after pulling that thin wrench hard enough to post that number?

Stanley isn't necessarily considered a top notch professional brand in the USA anymore, but they still produce and sell high end expensive tools under the Stanley name in other parts of the world.

All the Stanley tools I see anymore are made in Taiwan or China. However, I was in Ecuador a couple years ago doing some mission work on an orphanage in a small town. Ended up also doing some work on one of their vehicles and had to buy some wrenches at the local hardware/herramienta store. Ironically, their top brand was Stanley...(wait for it)...USA.
