Introduction：
DIN912 hexagon socket head cap screws are cylindrical head screws with an internal hexagonal drive suited for a hex / Allen key or wrench.
DIN 912 and ISO 4762 are equivalent standards, with the only difference in the standards themselves being that some nominal sizes were cut and that a fine thread standard (ISO 12474) was created.
