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.

Stainless Steel Socket Head Screws
 |  |
Fully Threaded | Partially Threaded |
These screws won't rust or corrode when exposed to moisture and chemicals. Their deep, six-point socket keeps hex keys from slipping out and damaging the drive.
Length is measured from under the head.
18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they don't hold up to the harsh chemicals that 316 stainless steel screws can.
