Lily A. ★★★★★

The nylon pellet locking feature on these flat head screws really holds tight in my precision assembly jig, and the black oxide finish looks clean against the steel. They threaded in smoothly without any galling, which is exactly what I needed for a repetitive tooling setup.

David ★★★★★

I replaced some worn set screws on a jig with these, and the black oxide finish seems more durable than the plain steel ones I had before. The hex socket drive seats perfectly with a standard wrench, making installation quick. For the price per pack, these are exactly what I needed for shop tooling.

Joshua ★★★★★

The hex socket drive seated perfectly on my driver, and the black oxide finish held up through a full day of fixture assembly without any wear. These are exactly the specs I needed for my jig build, and the 100-pack means I’ve got spares for the next project.
