Customer Reviews (4.2 / 5 · 5 reviews)

Eli C. ★★★★★

The black oxide finish on these screws is really clean and uniform, and they threaded into my jig perfectly without any binding. I used about half the pack for a small tooling project and every one seated smoothly with just a hex driver.

Sophia ★★★★★

I needed a handful of these for a small jig build, and the black oxide finish looks clean with no burrs. The hex socket drive seated firmly with my Allen key, and the threads felt precise right out of the bag.

Joshua Q. ★★★★☆

The nylon patch on these is a nice touch—they held snug in my tooling plate without loosening during a full day of runs. Only gripe is the black oxide finish scuffs a bit if you’re not careful with the hex key, but for the price per hundred, they’re solid.
