Socket head cap screw DIN 912 / ISO 4762, hex socket AF 10, M 12x140, steel 10.9 plain (black)

Where the screw head has to disappear flush into a counterbore, this DIN 912 socket head cap screw works with M 12 and 140 mm length. Head diameter 18.0 mm and head height 12.0 mm define the counterbore, and the tool engages in the AF 10 hex socket. The material is steel 10.9 plain (black).

Benefits

• Size M 12 transmits high clamping forces, and the AF 10 hex socket takes the required tightening torque.
• Property class 10.9 allows higher preload than 8.8 at the same size M 12.
• The AF 10 hex socket transmits the tightening torque without wrench flats on the head.
• A thread length of at least 36 mm within 140 mm overall length leaves a plain shank section.

Applications

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

Standards and conformity

The screw is dimensioned to DIN 912 and ISO 4762, which allows replacement of like-for-like parts in M 12. The material is stated as steel 10.9 plain (black).
