Claire ★★★★★

The hex socket drive makes installation really smooth, and the 316 stainless finish gives them a clean, professional look. I used these on a custom jig and they fit perfectly.

Zoe ★★★★★

These little 3/8-16 socket cap screws are perfect for a jig I’m building, and the 316 stainless feels substantial. The hex drive engages cleanly with no wobble, and the full threading makes them grip nicely. A solid choice for precision work.

Christopher B. ★★★★★

Finally, a hex drive screw that my Allen wrench bites into perfectly without camming out. The 316 stainless steel gave me confidence using these on a marine lift, and the thread engagement on this fully threaded 3/8-16 is spot on.
