ActiveFasteners—Hexalobular socket screws—Part 1: Countersunk flat head screws with reduced loadability
紧固件 内六角花形螺钉 第1部分：降低承载能力内六角花形沉头螺钉
Application Summary AI generated
This standard specifies the dimensional, mechanical, and performance requirements for countersunk flat head screws with a hexalobular socket drive designed for reduced loadability. It is applied in mechanical assemblies where space constraints or material thickness limitations require a lower-strength fastener to prevent damage to the mating component, such as in electronics, automotive interiors, or thin-sheet metal applications. The standard ensures interchangeability and consistent quality for these specialized screws in industrial manufacturing and procurement contexts.
