Customer Reviews (4.6 / 5 · 5 reviews)

Jason ★★★★★

Installed these on a jig I'm building and the hex socket drive held up perfectly with no stripping. The zinc plating looks clean and consistent across all 100 screws.

Samuel I. ★★★★★

I needed some quality fasteners for a jig I was building, and these zinc-plated screws came with a nice even finish and threaded cleanly into every hole. The hex socket drive grabbed perfectly with my hex key without any stripping.

Eva T. ★★★★★

The flat head sits perfectly flush in my jig fixture, which is exactly what I needed for a clean assembly. The zinc plating on all 100 pieces was uniform with no rough edges, and the hex socket drove smoothly every time.
