Socket head cap screw DIN 912 / ISO 4762, hex socket AF 17, M 20x100, steel 12.9 plain (black)

For M 20 joints with 100 mm length, this socket head cap screw to DIN 912 and ISO 4762 brings a cylindrical head of 30.0 mm diameter. The AF 17 hex socket transfers the tightening torque. It is made of steel 12.9 plain (black).

Benefits
