Socket head cap screw DIN 912 / ISO 4762, hex socket AF 3, M 4x16, steel 10.9 plain (black)

For M 4 joints with 16 mm length, this socket head cap screw to DIN 912 and ISO 4762 brings a cylindrical head of 7.0 mm diameter. The AF 3 hex socket transfers the tightening torque. It is made of steel 10.9 plain (black).

Benefits

• Dimensions to DIN 912 and ISO 4762, therefore interchangeable with existing M 4 joints.
• The AF 3 hex socket transmits the tightening torque without wrench flats on the head.
• Property class 10.9 allows higher preload than 8.8 at the same size M 4.
• The thread running nearly up to the head uses the full length of 16 mm for engagement.

Applications

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