Customer Reviews (4.8 / 5 · 5 reviews)

Thomas ★★★★★

The hex socket drive is ridiculously convenient for tight spots, and the nylon patch holds them snug even under vibration. I’ve used a handful on a jig I’m building and they thread in clean without binding. Exactly the kind of bulk pack I needed for precision work.

Daniel W. ★★★★★

I was worried about stainless steel screws snapping during assembly, but the nylon patch holds these securely in place while still allowing smooth hex drive insertion. The threads are clean and uniform across all 2000 pieces, making them perfect for jig work.

George ★★★★★

Exactly what I needed for mounting brackets on my CNC machine—the hex socket drive makes tightening them in tight spaces a breeze. The 18/8 stainless steel feels solid and corrosion-resistant, and a full 2000-count bag means I'm set for years.
