The nylon pellet in these is a lifesaver for holding adjustment positions without loosening under vibration, and the black oxide finish looks clean on my fixture. I’ve used about thirty so far for jig assembly and not a single stripped hex socket, which is more than I can say for cheaper packs. Soli

These button head screws are perfect for my fixture builds, and the black oxide finish looks great while resisting corrosion. The hex socket drive makes them easy to install even in tight spots, and each one threads smoothly. I’m glad I grabbed a full pack for all my upcoming projects.

The nylon pellet adds a nice touch for holding set screws in place, and the black oxide finish made them look clean on my drill press jig. These feel solid for the price and fit standard 1/4-20 threads perfectly.
