cheers
Yes, worn from use on and off. New, one time, cant say I can recall.

Impersonator nut = China junk, think China bulk nuts on low end consumer crap.

I found fasteners can be allot like allot of other things in life, you get what you pay for. Fasteners can be extreme from one end of the spectrum to the other. I wont put nyloks on anything probably because I dont have ready access to the real deal, and just about everything I play with involves heat at some point, and Im too lazy to try and figure it out on the web who is selling the real McCoy vs the garbage.

Ever since Fastenal went to world wide sourcing, they blew my methodology of just buying USA fasteners as a means to find a quality fastener, now its just too much work to sift through all the chaff looking for some grain.

At one time, if I could not get it with a Rockford head stamp, as far as " standard " fasteners to stock, I would not buy, and now I cant even find them, dont know if they stopped manufacturing and started selling Asian shit or what.

And then when you do buy a box of bolts you end up getting some other sourced bolts, because they have not updated their cataloging. Its a pig in a poke. I dont like pigs in a poke.

I don't believe in using lock washers at all but those look interesting.

They're called "Stover Lock Nuts" and they are significantly more reliable than regular nyloks.

Nyloks are just one of many different ways of preventing a bolted fastening from backing off while in use. They're fine for many applications but they do have they're limitations. In addition to the fact that they will back off under exteme use they're not usually found in higher grades. I suspect that most of the off the shelf nyloks out there are only Grade 2. If you look you can find them in Grade 5 but not many places carry them.

As you move into different locking methods like the Stovers you get not only a more secure locking method but a stronger nut to boot. Castellated nuts provide a positive locking method but some are only low grade so if you need high strength and high security you need to make sure you're buying a good grade.

No industry pays more attention to fastener locking than the aviation world (I'm sure Red will agree) and there are a myriad of possibilities. The link below describes a number of nuts used in aviation--I've used a bunch over the years but there are some in there that I've never heard of...

I never knew they were called Stover nuts, but I've worked on automobiles for many a year, and they are used on the exhaust manifolds. I've never seen one come loose, and one usually twists the stud off when removing them while doing exhaust work. So there I was, laying under the vehicle with a drill, reaming out the hole and chasing that spiral of old stud material (if I was lucky) out of the manifold. (uphill, and into the rain, right?)

$10 for 10 pairs in 3/8". Glad I do not need something for the stuff I build like that.

Keith,

I printed out a copy of that rundown, for inclusion in the "neat shop stuff" folder on the wood working bench folder ready reference rack.

The best apprentice guide to self lockers I've seen, the pictures tell all.

Thanks
