Socket head cap screw DIN 912 / ISO 4762, hex socket AF 2.5, M 3x25, steel zinc plated 8.8

The AF 2.5 hex socket in the cylindrical head lets this M 3x25 screw to ISO 4762 be fitted where no wrench can reach the side of the head. At 5.5 mm head diameter and 3.0 mm head height the joint stays flat. The material is steel zinc plated 8.8.

Benefits

• The AF 2.5 hex socket transmits the tightening torque without wrench flats on the head.
• Head diameter 5.5 mm and head height 3.0 mm to DIN 912 fit into a cylindrical counterbore.
• The thread running nearly up to the head uses the entire length of 25 mm for engagement.
• Property class 8.8 with electroplated zinc coating as surface protection.
• Dimensions to DIN 912 and ISO 4762, therefore interchangeable with existing M 3 joints.
