Eli ★★★★★

Using these for a marine railing project, the hex socket drive made installation in tight spots a breeze. The 316 stainless seems like it will hold up well to the saltwater.

Emma ★★★★★

The 316 stainless steel feels substantial, and the cup point grips securely without stripping the surface. I used these for a jig build, and the hex socket drive made installation effortless in a cramped spot.

George E. ★★★★★

Needed set screws for a marine project and these M4 20mm cup point ones fit perfectly. The hex socket drive made it easy to tighten them in a tight spot without stripping.
