Customer Reviews (4.8 / 5 · 5 reviews)

Victoria ★★★★★

I've been using these for fixturing on my mill, and the nylon pellet is a nice touch for locking them in place without needing thread locker. The black oxide finish seems durable so far, and they drive smoothly with a hex key.

Madison ★★★★★

The black oxide finish on these is flawless—no chips or uneven spots across all 25, and the nylon pellet locks them in place perfectly for my jig setup. Threads cut clean and the hex socket seated every driver bit without any slop. Exactly what precision assemblies need.

Sofia D. ★★★★★

I needed some black oxide screws for a jig I'm building, and these are perfect. The hex socket drive made installation very smooth, and the nylon pellet locking feature held tight.
