Socket head cap screw DIN 912 / ISO 4762, hex socket AF 3, M 4x45, steel 12.9 plain (black)

Where the screw head has to disappear flush into a counterbore, this DIN 912 socket head cap screw works with M 4 and 45 mm length. Head diameter 7.0 mm and head height 4.0 mm define the counterbore, and the tool engages in the AF 3 hex socket. The material is steel 12.9 plain (black).

Benefits

• A thread length of at least 20 mm within 45 mm overall length leaves a plain shank section.
• Property class 12.9 offers the highest strength in this range at the same size M 4.
• Head diameter 7.0 mm at 4.0 mm head height to DIN 912, matching a cylindrical counterbore.
• The AF 3 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
