Re: nylock vs. lock washer...which is best?

Not surprising that the lock washer case came loose. The washer wasn't completely compressed. He should have done this test with the recommended torque of 31 Ft-Lbs for this type fastener.

Re: nylock vs. lock washer...which is best?

.

Agreed...more torque would have definitely made a difference. The video is far more interesting at 6lbs though!

Another issue that stands out is...those nylock nuts I've dealt with required more than 6lbs just to turn so trying to torque them down at such a low value seems inaccurate at best.

Re: nylock vs. lock washer...which is best?

I actually posted that as a comment in the video when I first saw it. It's impossible to test a fastener's holding power unless it's properly torqued.

Right, he completely ignored the running torque of the nylock nut.

agree.

I wonder if he's tested torque nuts? Bet they beat nylon/split washer to )_&_&+, though been wrong before.

Re: nylock vs. lock washer...which is best?

OK, I had to go look that up. I've seen those used on truly ancient MOPAR products, like my dad's '51 Dodge truck- "ancient" meaning that that truck was one year older than I. Dodge Bros did things a bit differently, like left hand threads on the left side of the vehicle. They may have worked better, I have no idea. I note that cotter pins are far more common now, and MOPAR has gone to all right hand threads(?).

Moot point and a waste of a video and everybodys time if the fastener was not torqued to specs
