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.
Cadmium-Plated Alloy Steel—The plating reduces friction between the screw and your mounting surface to prevent sticking when you tighten or loosen them. It also creates a barrier against rust.
Military Specification—Manufactured and tested to meet strict U.S. military standards for material and construction.

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.
High-Temperature High-Strength A286 Stainless Steel—Often used to fasten parts in engines and turbines, these are our strongest stainless steel screws. They withstand higher temperatures than 18-8 stainless steel screws and resist corrosion from chemicals, such as bleach and chlorine. However, they won't hold up to salt water as well as 316 stainless steel screws.
Military Specification—Manufactured and tested to meet strict U.S. military standards for material and construction.
