Customer Reviews (4.8 / 5 · 5 reviews)

Brian ★★★★★

Pulled these out of the package for a jig I'm building and the hex socket drive bit cleanly without any stripping. The alloy steel feels dense and the black oxide coating is uniform across all 300 pieces, so no hunting for a bad one in the batch.

Kevin ★★★★★

The black oxide finish on these screws made them slide right into the pre-tapped holes on my milling fixture without any binding, and the hex socket drive grabbed perfectly with my Allen key. Each one feels solid and well-made, exactly what I needed for a heavy-duty tooling project.

Mia ★★★★★

The black oxide finish looks great and seems durable for tooling use. Tapped them into a fixture plate and all 300 seated cleanly without any binding.
