精密机械用紧固件 十字槽自攻螺钉 刮削端
Application Summary AI generated
This standard specifies the dimensions, technical requirements, and marking of cross-recessed tapping screws with a scrape point, designed for use in fine mechanical assemblies. It is applied in the manufacturing of precision instruments, optical devices, and small electronic equipment where secure thread-forming in thin metal or plastic components is required without pre-tapped holes. The scrape point feature facilitates easier insertion and reduces driving torque in these delicate applications.
