Steel Torx Plus Flat Head Screws

The strongest Torx Plus flat head screws we offer. They're made of alloy steel, so they have nearly twice the tensile strength of other screws. With larger lobes than Torx drives, Torx Plus withstands even more torque without slipping and stripping the drive.

Length is measured from the top of 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.

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

Stainless Steel Torx Plus Flat Head Screws

The most corrosion-resistant Torx Plus 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 larger lobes than Torx drives, Torx Plus withstands even more torque 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.
