Hannah N. ★★★★★

The hex socket drive made installation easy with my allen wrench, and the thermal black oxide coating gives these a nice, consistent finish without any burs. Perfect for my jig setup where I needed the nylon pellet to lock the threads in place.

Eva ★★★★★

I needed some heavy-duty fasteners for a jig I was building, and these alloy steel screws with the nylon pellet held tight without loosening during vibration testing. The black oxide finish also helped them resist corrosion better than the plain steel ones I used before.

Andrew ★★★★★

The hex socket drive grabbed securely without stripping, and the nylon pellet adds a nice vibration resistance for jig setups. I've used a dozen already and every one threaded smoothly into pre-tapped holes. Exactly what I needed for heavy-duty fixtures.
