Comments about Jamestown Distributors S/S Lock Nuts:
Needed to secure a bolt in a fan used for dance. The hinge got heavy use and the regular nut would come loose and fall off. Using two nuts together wouldn't do the trick so I went looking for a lock nut. Finding the size I needed was a challenge. Not everyone stocks a #4-40. Found this site and waited for a backorder to come in and couldn't be happier with what I received. I'll use this little gem in my woodworking projects, too.
