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.

Stainless Steel Torx Flat Head Screws

The most corrosion-resistant Torx flat head screws we offer. Made of stainless steel, they won't rust or corrode when exposed to moisture and chemicals. With a deep six-lobe opening, these screws prevent slipping and stripping drives. Also known as star drives, they withstand more torque than slotted, Phillips, and hex drives.

Length is measured from the top of the head.

High-Temperature High-Strength A286 Stainless Steel—These screws are stronger than 18-8 stainless steel and withstand higher temperatures. They also resist corrosion from chemicals, such as bleach and chlorine, but they won't hold up to salt water as well as 316 stainless steel.

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

Stainless Steel Button Head Torx Screws

Our most corrosion-resistant button head Torx screws. The button head looks similar to a pan head, but it's lower and more compact, taking up less space. With a deep six-lobe opening, the Torx drive prevents your driver from slipping and stripping the drive. Also known as star drives, they withstand more torque than slotted, Phillips, and hex drives.

Length is measured from under the head.

High-Temperature High-Strength A286 Stainless Steel—These screws are stronger than 18-8 stainless steel and withstand higher temperatures. They also won't corrode from chemicals, such as bleach and chlorine. However, they don't hold up to salt water as well as 316 stainless steel.
