Grade 8 Steel Hex Flange Screws

Product Description

ASME B 18.2.1 - 2010 Hex Flange Screws

 QBH Made from Grade 8 steel, these screws can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are at least 25% stronger than medium-strength steel screws. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. Material meets SAE J429 specifications for quality. Dimensions meet IFI 111 specifications. Grade 8 steel hex head screws are marked with six radial lines. Head height includes the flange. Length is measured from under the flange.

     Black-phosphate steel screws are mildly corrosion resistant in dry environments. Zinc yellow-chromate plated steel screws resist corrosion in wet environments.

     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
