About Socket Cap Screws

These screws don't require side clearance for a wrench, so they're good for tight spots. Install them with a hex key. The screw head sits atop the fastened material or can be sunk into a counterbored hole.

Fasten thin materials and other surfaces that can't be counterbored. Button head screws have a low-profile, rounded head that fits snugly to fastened surfaces and provides a neat appearance.
