Socket head cap screw DIN 912 / ISO 4762, hex socket AF 3, M 4x16, steel 12.9 plain (black)

For screw joints with an M 4 thread and 16 mm shank length, this socket head cap screw to DIN 912 provides an AF 3 hex socket. At 7.0 mm head diameter and 4.0 mm head height the joint stays flat. Supplied in steel 12.9 plain (black).

Benefits

• The AF 3 hex socket transmits the tightening torque without wrench flats on the head.
• Head diameter 7.0 mm and head height 4.0 mm to DIN 912 fit into a cylindrical counterbore.
• The thread running nearly up to the head uses the entire length of 16 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 4 joints.

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