Customer Reviews (4.6 / 5 · 5 reviews)

Sophia A. ★★★★★

I needed some low-profile fasteners for a jig repair and the black oxide finish on these makes them look clean against the steel. They threaded smoothly into pre-tapped 1/4-28 holes without any binding.

Stella T. ★★★★★

These button head screws fit perfectly into my jig fixture and the black oxide finish holds up well against light oils. The hex socket drive made installation quick with no stripping issues.

Chloe ★★★★★

I was swapping out some worn screws on an old fixture, and these button heads seated perfectly with my hex driver. The 1/4-28 threads engaged smoothly, and the black oxide finish looks professional and seems like it'll resist rust better than plain steel.
