Hi Jim.
Please see http://we-llc.com/WEEBLug_story.html. You can certainly repeat the test in your own lab.
What we were trying to point out is that the
contact area for 2 threads of a thread forming screw do not match the
rating of the lug. The lug does meet the UL467 standard, but the lug
plus thread forming screw does not.
Best Regards,

After a quick search of Brian Wileys www site we-llc, I could not find
the video clip that allegedly shows the traditional burial-rated ground
lug frying its mounting screw at its rated ampacity. Has this
controversy been cleared up or just vanished due to lack of interest?
