Stainless Steel Slotted Flat Head Screws

The most corrosion-resistant slotted flat head screws we offer. Made of stainless steel, they won't rust or corrode when exposed to moisture or chemicals. With only two contact points, the slotted drive is the most basic drive style. The slot can't withstand much torque, so it's best to hand-tighten them instead of using power tools.

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.

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

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

Steel Slotted Flat Head Screws

A simple yet effective drive style for light duty tasks. With only two contact points, the slotted drive is the most basic drive style. The slot can't withstand much torque, so it's best to hand-tighten them instead of using power tools.

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.

Brass Slotted Flat Head Screws

Conductive and nonmagnetic, these slotted screws are often used to secure electrical equipment, such as circuit boards, inside enclosures. Made of brass, they also resist corrosion in humid environments. With only two contact points, the slotted drive is the most basic drive style. The slot can't withstand much torque, so it's best to hand-tighten them instead of using power tools.

Length is measured from the top of the head.

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