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—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.

Steel Cup-Tip Set Screws

Made of alloy steel, these screws are strong enough to hold components without wearing down. The tip has thin edges that dig into surfaces for a secure hold. They often lock gears, pulleys, and other transmission components onto shafts.
