William N. ★★★★★

The nylon patch on these is a nice touch—they hold snugly under vibration without needing loctite. The 18/8 stainless finish is clean and consistent across all 100 pieces, and the hex socket drive seats perfectly every time. Exactly what I wanted for jig assembly.

Joshua Z. ★★★★★

I needed partially threaded screws for a metal fixture, and these fit perfectly with the nylon patch holding firm during assembly. The 18/8 stainless steel feels sturdy and hasn't shown any signs of corrosion yet.

Natalie ★★★★★

Finally got these for a jig I was building and the 18/8 stainless is exactly what I needed for outdoor use. The hex socket drive seated perfectly without any stripping.
