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.

Black-Oxide 18-8 Stainless Steel—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They resist rust in wet and outdoor environments, but they don't hold up to the harsh chemicals that 316 stainless steel screws can.

Chrome-Plated 18-8 Stainless Steel—The brightest, shiniest finish we offer, with a mirror-like appearance often used in decorative applications. These screws also won't rust in wet and outdoor environments.

Silver-Plated 18-8 Stainless Steel—The silver plating helps these screws thread on smoothly during installation. They also won't rust in wet and outdoor environments.

Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel screws, these screws won't degrade when exposed to harsh weather, salt water, and most chemicals.

High-Strength Highly Corrosion-Resistant 316 Stainless Steel—Cold-worked, so they're 60% stronger than other 316 stainless steel screws. These screws are superior to 18-8 stainless steel screws because they won't degrade when exposed to harsh weather, salt water, and most chemicals. For even higher strength, choose screws made from A286 stainless steel.

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.
