Socket head cap screw DIN 912 / ISO 4762, hex socket AF 4, M 5x70, 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 5 and 70 mm length. Head diameter 8.5 mm and head height 5.0 mm define the counterbore, and the tool engages in the AF 4 hex socket. The material is steel 10.9 plain (black).

Benefits

• A thread length of at least 22 mm within 70 mm overall length leaves a plain shank section.
• Property class 10.9 allows higher preload than 8.8 at the same size M 5.
• Head diameter 8.5 mm at 5.0 mm head height to DIN 912, matching a cylindrical counterbore.
• The AF 4 hex socket transmits the tightening torque without wrench flats on the head.
• Size M 5 covers the most common range in fixture building, and the AF 4 hex socket is a standard tool size.

• Drive and gearbox engineering
• Clamping fixtures in tool making
• Hydraulic and pneumatic power units
