Socket head cap screw DIN 912 / ISO 4762, hex socket AF 10, M 12x20, steel plain (black) 8.8

This version in steel plain (black) 8.8 covers the M 12 thread at 20 mm length. The cylindrical head with 18.0 mm diameter and 12.0 mm height takes an AF 10 hex socket, so no wrench flats are needed on the head.

Benefits

• The AF 10 hex socket transmits the tightening torque without wrench flats on the head.
• Size M 12 transmits high clamping forces, and the AF 10 hex socket takes the required tightening torque.
• Head diameter 18.0 mm at 12.0 mm head height to DIN 912, matching a cylindrical counterbore.
• Property class 8.8 in plain finish for protected or oily installation points.
• The thread running nearly up to the head uses the full length of 20 mm for engagement.

Applications

• Bolting of flanges and covers
• Frame and profile structures
• Tool and mould making
• Machine and fixture building
