Steel Socket Head Screws

Fully Threaded |

Partially Threaded |
Made of alloy steel, these screws are the standard for high-strength fastening. Use them in high-load applications such as dies, presses, and heavy equipment. The deep, six-point socket keeps the hex key from slipping out and damaging the drive.
Length is measured from under the head.
Black-Oxide Alloy Steel—Best for dry environments since moisture will cause these screws to rust. They have a dark, matte appearance.
