Customer Reviews (4.8 / 5 · 5 reviews)

Elizabeth ★★★★★

The hex socket drive made them easy to install in my jig without stripping, and the black oxide finish looks clean. A solid pack of hardware for precision work.

Ella ★★★★★

I needed some button head screws for a small jig I was building, and the fully threaded shank on these made alignment a breeze. The hex socket drive grabbed perfectly without any stripping, and the 100-pack is great value for the price.

William O. ★★★★★

The black oxide finish on these screws looks really clean and professional, and the nylon pellet holds tight even after multiple adjustments on my jig. They threaded smoothly into my 3D printer’s metal frame without any binding issues.
