The most corrosion-resistant fillister head slotted screws we offer. With a deeper drive than others, fillister heads reduce the likelihood that basic slotted drivers slip as you hand-tighten them. Since they also have a narrow diameter, they fit into tight spaces, such as holes tucked away inside machinery.

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.
