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.

Stainless Steel Hex-Drive Flat Head Screws

The most corrosion-resistant hex-drive flat head screws we offer. Made of stainless steel, they won't rust or corrode when exposed to moisture and chemicals, but they're not as strong as alloy steel. With six contact points, the hex drive withstands more torque than slotted and Phillips to securely grip your driver without slipping and stripping the drive.

Length is measured from the top of 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 can.

Standard Profile—Standard-profile heads are the most common choice for flat head screws.

Military Specification—These screws are manufactured and tested to meet strict U.S. military standards for material and construction.

Stainless Steel Cup-Tip Set Screws

These corrosion-resistant cup-tip screws grip parts tightly. Made of stainless steel, they won't rust, but they're not as strong as alloy steel. The tip has thin edges that dig into surfaces for a secure hold. They often lock gears, pulleys, and other transmission components onto shafts.

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 can.

Military Specification—These screws are manufactured and tested to strict U.S. military standards for material and construction.
