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.

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.
