Stainless Steel Hex Flange Bolt with Serrated Glutge Cap Screw

Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. Serrations under the head grip the material surface for mild vibration resistance, and the flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. Head height includes the flange. Length is measured from under the flange.

Match the thread spacing of mating components. 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.
