Socket head cap screw DIN 912 / ISO 4762, hex socket AF 2.5, M 3x30, steel zinc plated 8.8

This socket head cap screw to DIN 912 joins components with the M 3 thread over a length of 30 mm. It is tightened through the AF 2.5 hex socket, and the head measures 5.5 mm in diameter at 3.0 mm height. The specified material is steel zinc plated 8.8.

Benefits

• Head diameter 5.5 mm at 3.0 mm head height to DIN 912, matching a cylindrical counterbore.
• The thread running nearly up to the head uses the full length of 30 mm for engagement.
• Size M 3 with only 5.5 mm head diameter saves space on tight hole patterns.
• The AF 2.5 hex socket transmits the tightening torque without wrench flats on the head.
• Dimensions to DIN 912 and ISO 4762, therefore interchangeable with existing M 3 joints.

Applications

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