Eliminate the need for a separate washer—these screws distribute pressure where the screw meets the surface without taking up as much space as a washer. Made of alloy steel, they are stronger than stainless steel screws. Their black-oxide finish provides mild corrosion resistance in dry environments. Head height includes the flange. Length is measured from under the flange.

Coarse threads are the industry standard; choose these screws if you don’t know the pitch or the threads per inch. Fine threads are closely spaced to prevent loosening from vibration. They are not compatible with coarse threads.

Exact-Grip-Length Flanged Socket Head Screws

For use where sideways forces are a concern, these screws have a precisely measured unthreaded portion (grip) for a strong hold. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. Head height includes the flange. Length is measured from under the flange.

Coarse threads are the industry standard; choose these screws if you don’t know the threads per inch. Fine threads are closely spaced to prevent loosening from vibration. They are not compatible with coarse threads.

Serrated-Flange Socket Head Screws

Fully Threaded

Partially Threaded

Serrations under the head grip the material's surface for mild vibration resistance, and the flange distributes pressure, eliminating the need for a separate washer. With a tensile strength of 140,000 psi, these alloy steel screws are comparable in strength to Grade 8 steel screws and are stronger than stainless steel screws. Their black-oxide finish provides mild corrosion resistance in dry environments. Head height includes the flange. Length is measured from under the flange.
