Socket head cap screw DIN 912 / ISO 4762, hex socket AF 17, M 20x100, steel zinc plated 8.8

Where the screw head has to disappear flush into a counterbore, this DIN 912 socket head cap screw works with M 20 and 100 mm length. Head diameter 30.0 mm and head height 20.0 mm define the counterbore, and the tool engages in the AF 17 hex socket. The material is steel zinc plated 8.8.
