Customer Reviews (4.6 / 5 · 5 reviews)

Alexander ★★★★★

Hex socket drive grabbed the allen key perfectly, no stripping even under heavy torque. The 18/8 stainless finish is clean and corrosion-resistant for workshop use. Exactly what I needed for a precision assembly.

Lily H. ★★★★★

I needed a batch for a jig I’m building, and these screws threaded cleanly into tapped holes without any binding. The 18/8 stainless seems solid, and the hex socket drive held the bit firmly during tightening.

Evelyn X. ★★★★★

I needed replacements for some jig hardware and these socket cap screws fit perfectly. The hex drive seats nicely without stripping, and the stainless steel finish is clean and uniform across all 100 pieces.
