They work way good! No complaints

I recently purchased the 100-piece set of M3 x 0.5mm 304 Stainless Steel Self-Lock Nylon Inserted Hex Lock Nuts for a project, and they have performed admirably. These lock nuts are well-constructed, showcasing both the durability and quality I was looking for. The locking capability of these nuts is quite decent. The nylon inserts provide a good grip and ensure that the nuts stay in place once tightened. This feature gives me confidence in the security and stability of the connections in my projects. Additionally, the stainless steel material adds an extra layer of durability, making these nuts suitable for various applications where strength and longevity are required. Overall, I'm satisfied with these hex lock nuts. They are effective, reliable, and offer good value for the price. For anyone in need of quality self-locking nuts for their DIY or professional projects, I would recommend giving these a try.

Great low cost locking nuts.

Good quality

Little stainless steel bolts they are not magnetic so they’re not a low-grade stainless. That’s generally how you can check if a bolt is a low quality stainless it’ll be very magnetic when stainless steel should be non-magnetic

Excellent AAA+++++

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.

Bought these to use for my furitek Cayman Pro and the other FMS axles shiny chrome has nylon insert to keep it in place very good quality and quantity.
