Socket head cap screw DIN 912 / ISO 4762, hex socket AF 10, M 12x20, steel 12.9 plain (black)

This version in steel 12.9 plain (black) covers the M 12 thread at 20 mm length. The cylindrical head with 18.0 mm diameter and 12.0 mm height takes an AF 10 hex socket, so no wrench flats are needed on the head.

Benefits

• Head diameter 18.0 mm at 12.0 mm head height to DIN 912, matching a cylindrical counterbore.
• The thread running nearly up to the head uses the full length of 20 mm for engagement.
• Size M 12 transmits high clamping forces, and the AF 10 hex socket takes the required tightening torque.
• The AF 10 hex socket transmits the tightening torque without wrench flats on the head.

Applications

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

Standards and conformity

Head, AF 10 hex socket and M 12 thread follow DIN 912 in conjunction with ISO 4762. The material is documented as steel 12.9 plain (black).
