Customer Reviews (4.8 / 5 · 5 reviews)

Thomas ★★★★★

I’ve been using these for mounting brackets in my CNC jigs, and the Class 8.8 steel really holds up under heavy torque without deforming. The black oxide finish also resists fingerprints and rust better than I expected for the price.

Abigail C. ★★★★★

These are perfect for jig building—the hex socket drive makes it easy to get good torque in tight spots, and the black oxide finish feels durable. I just finished a batch of assembly fixtures with the full 800 count, and every single one threaded cleanly.

Aurora ★★★★★

I was worried about rust, but the black oxide finish on these M4 cap screws has held up perfectly in my shop. They drive smoothly with a hex key and the 12mm length is spot on for jig assembly.
