Stainless Steel Pan Head Slotted Screws

The most corrosion-resistant pan head slotted screws we offer. They have a moderate height and width profile, offering a middle ground between narrower button heads and wider truss heads. With only two contact points, the slotted drive can't withstand much torque, so it's best to hand-tighten them.

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 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.

Brass Pan Head Slotted Screws

These pan head slotted screws have a shiny look and won't rust in damp environments. Made of brass, they're also conductive and nonmagnetic, making them useful for electrical applications. Pan heads have a moderate height and width profile, offering a middle ground between narrower button heads and wider truss heads. With only two contact points, the slotted drive can't withstand much torque, so it's best to hand-tighten them.

Length is measured from under the head.
