Socket head cap screw DIN 912 / ISO 4762, hex socket AF 6, M 8x20, steel 12.9 plain (black)

The AF 6 hex socket in the cylindrical head lets this M 8x20 screw to ISO 4762 be fitted where no wrench can reach the side of the head. At 13.0 mm head diameter and 8.0 mm head height the joint stays flat. Made of steel 12.9 plain (black).

Benefits

• The AF 6 hex socket transmits the tightening torque without wrench flats on the head.
• Head diameter 13.0 mm and head height 8.0 mm to DIN 912 fit into a cylindrical counterbore.
• The thread running nearly up to the head uses the entire length of 20 mm for engagement.
• Property class 12.9, the highest class listed here, for high preload forces.
• Dimensions to DIN 912 and ISO 4762, therefore interchangeable with existing M 8 joints.

Applications

• Machine and fixture building
• Bolting of flanges and covers
• Frame and profile structures
• Highly preloaded joints in tool making
