Socket head cap screw DIN 912 / ISO 4762, hex socket AF 14, M 16x55, steel 10.9 plain (black)

This version in steel 10.9 plain (black) covers the M 16 thread at 55 mm length. The cylindrical head with 24.0 mm diameter and 16.0 mm height takes an AF 14 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 16.
• The AF 14 hex socket transmits the tightening torque without wrench flats on the head.
• Head diameter 24.0 mm at 16.0 mm head height to DIN 912, matching a cylindrical counterbore.
• Size M 16 transmits high clamping forces, and the AF 14 hex socket takes the required tightening torque.
• The thread running nearly up to the head uses the full length of 55 mm for engagement.

Applications

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