### ⭐⭐⭐⭐⭐ Tiny, but effective ...
*by G***E on October 15, 2024*

I purchased SS machine screws to fix a problem with my golf bag. One of the pins holding one of the folding legs fell out. I needed a self-locking nut because I couldn't tighten the fastener all the way as it would cause the leg to bind. Thus, a nylon insert self-locking nut seemed to be the best option. You receive a small container of nuts ... I was surprised how small the container was. Anyway, I just needed one but now I have an almost "infinite" supply.
