Chloe ★★★★★

I’m using these for a jig I’m building, and the nylon pellet locking feature is a nice touch—keeps the screws from backing out under vibration. The black oxide finish also looks clean and should resist corrosion well on the shop floor.

William A. ★★★★★

Needed some black oxide screws for a jig I’m building, and these button heads came in with a nice, even finish and no burrs on the threads. The hex socket drive feels solid and hasn’t stripped out, which is always my worry with smaller fasteners. For a hundred pack at this price, they’re exactly wha

Abigail L. ★★★★★

These button head screws worked perfectly for a jig I was building on my drill press. The black oxide finish seems durable and the nylon pellet is a nice touch for vibration resistance. Exactly the right size for the application I needed.
