engine and drivetrain Nord-lock washers

Has anyone used these Nord-Lock lock washers?

The youtube demo is pretty compelling. I asked for some samples, but thought there must be some engineering-types on our board who could help separate the snake-oil from useful hardware. Sure would make it easy to get rid of all the castellated and safety-wired nuts on the 2002.

they work great! especially on header bolts. Just make sure they are installed in pairs in the proper orientation. And make sure you use harder material that what you are bolting. for example, SS nord-lock for aluminum is okay but SS washers on hardened steel components will not work. I use the steel washers for everything. You can get them from www.mcmastercarr.com

Bosch uses these on the fasteners for their conveyor systems which typically have fastener loosening issues. They do work very well but as noted they must be harder than the material the fastener is made from. They are also not much thicker than the standard washer.

Thanks for the tips, I'll give their lock-washers a try.

Someone on S14power mentioned they "file into" the threads. But you saw that.
