Sophia V. ★★★★★

Picked up these 4-BA screws for a jig I’m building, and the black oxide coating looks clean and feels durable—no rust worries so far. The hex drive seated perfectly with my Allen key, threading smoothly into the tapped holes. Exactly what I needed for precise assembly work.

Matthew ★★★★★

I needed some small socket cap screws for a jig I was building, and these 4-BA x 5/8" ones fit perfectly in the hex driver without any wobble. The threads cut cleanly into the alloy steel, and the black oxide has a nice, uniform matte look that resists glare.

Julian A. ★★★★★

The black oxide finish gave these screws a nice, even look and seems like it'll resist corrosion well in my jig setup. I was pleased that the threads were clean and started easily in pre-tapped holes without binding. For precision work, having a full 200 count in one pack is really convenient.
