QSC 3/8-24 Steel Right Hand Jam Nut, Clear Zinc Plated (6-Pack)

It's a jam nut. It does the job it's meant for. I'm using it with a rod end bearing in a knife filing jig, so it's not under high stress. It does keep the jig height adjusted so the angle is consistent

Great product, great price.

as expected

Worked great just what I needed
