Jam Nut


its a nut.... works great. better than a crush washer

Worked, hope it was made in USA

by -

I believe this was made in USA...that is the only reason I bought it. From what I read this was made by JP Enterprises...I hope that is correct, because that is the only reason I paid this much. Could have had it for less, but I want to support US business....Anywho, it worked.
