Socket head cap screw DIN 912 / ISO 4762, hex socket AF 12, M 14x20, steel zinc plated 8.8

This version in steel zinc plated 8.8 covers the M 14 thread at 20 mm length. The cylindrical head with 21.0 mm diameter and 14.0 mm height takes an AF 12 hex socket, so no wrench flats are needed on the head.

Benefits

• Size M 14 transmits high clamping forces, and the AF 12 hex socket takes the required tightening torque.
• The thread running nearly up to the head uses the full length of 20 mm for engagement.
• Head diameter 21.0 mm at 14.0 mm head height to DIN 912, matching a cylindrical counterbore.
• Property class 8.8 with electroplated zinc coating as surface protection.
• The AF 12 hex socket transmits the tightening torque without wrench flats on the head.

Applications

• Conveying technology and plant construction
• General assembly in equipment building
• Bolting of covers and sheet metal
• Machine frames and stands

Standards and conformity

The screw is dimensioned to DIN 912 and ISO 4762, which allows replacement of like-for-like parts in M 14. The material is stated as steel zinc plated 8.8.
