Steel Torx Flat Head Screws

Get a grip with less slip. 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.

Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.

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

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.

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.
