Socket head cap screw DIN 912 / ISO 4762, hex socket AF 12, M 14x25, steel plain (black) 8.8

Where the screw head has to disappear flush into a counterbore, this DIN 912 socket head cap screw works with M 14 and 25 mm length. Head diameter 21.0 mm and head height 14.0 mm define the counterbore, and the tool engages in the AF 12 hex socket. The material is steel plain (black) 8.8.

Benefits

• The AF 12 hex socket transmits the tightening torque without wrench flats on the head.
• Head diameter 21.0 mm at 14.0 mm head height to DIN 912, matching a cylindrical counterbore.
• Dimensions to DIN 912 and ISO 4762, therefore interchangeable with existing M 14 joints.
• The thread running nearly up to the head uses the full length of 25 mm for engagement.
• Size M 14 transmits high clamping forces, and the AF 12 hex socket takes the required tightening torque.

Applications

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

Standards and conformity

Head, AF 12 hex socket and M 14 thread follow DIN 912 in conjunction with ISO 4762. The material is documented as steel plain (black) 8.8.
