    Specification

    DIN912 High Tensile Stainless Steel Bolts

    Socket head cap screws are commonly used in machine assembly for removable panels and parts. They have a round cap with a hex head and are tightened with a socket wrench drive. Longer caps are easier to see when fastened, while button and flat head caps are less likely to snag clothing or linkages. Cap screws with a black oxide or armor coat finish resist corrosion.

    Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads

    per inch. Fine and extra-fine threads are closely spaced to prevent loosening from vibration; the finer

    the thread, the better the resistance. They are not compatible with coarse threads.

    Screws that meet ASTM A574, ASTM A574M, and ISO 898-1 comply with specifications and testing

    requirements for material quality. Screws that meet ASME B18.3, ASME B18.3M, ISO 21269, and

    ISO 4762 (formerly DIN 912) comply with specifications for dimensional standards.
