Customer Reviews (4.6 / 5 · 5 reviews)

Edward ★★★★★

Decided to swap out the standard cap screws on my jig fixture, and these low-profile ones fit perfectly where clearance was tight. The hex socket drive bites well without stripping.

Ruby ★★★★★

The low head profile let me use these in a tight spot where standard cap screws would have stuck out too far. Black oxide finish looks clean and held up well during assembly. Pack of 300 should last me through several projects.

Daniel ★★★★★

Needed these for a precision jig project and the low head profile made all the difference in tight spaces. The black oxide finish looks consistent across all 300 pieces, which is a nice touch.
