Socket head cap screw DIN 912 / ISO 4762, hex socket AF 2.5, M 3x16, steel 10.9 plain (black)

This socket head cap screw to ISO 4762 creates the M 3 connection over 16 mm of length. The AF 2.5 hex socket sits in the head, which measures 5.5 mm across and stands 3.0 mm high. The screw is made of steel 10.9 plain (black).
