Socket head cap screw DIN 912 / ISO 4762, hex socket AF 12, M 14x55, steel 10.9 plain (black)

This version in steel 10.9 plain (black) covers the M 14 thread at 55 mm length. The cylindrical head with 21.0 mm diameter and 14.0 mm height takes an AF 12 hex socket, so no wrench flats are needed on the head.

Benefits

• Property class 10.9 allows higher preload than 8.8 at the same size M 14.
• The AF 12 hex socket transmits the tightening torque without wrench flats on the head.
• Head diameter 21.0 mm at 14.0 mm head height to DIN 912, matching a cylindrical counterbore.
• Size M 14 transmits high clamping forces, and the AF 12 hex socket takes the required tightening torque.

Applications

• Drive and gearbox engineering
• Clamping fixtures in tool making
• Hydraulic and pneumatic power units
• Highly loaded flange joints

Standards and conformity

Head, AF 12 hex socket and M 14 thread follow DIN 912 in conjunction with ISO 4762. The material is documented as steel 10.9 plain (black).
