Socket head cap screw DIN 912 / ISO 4762, hex socket AF 17, M 20x55, stainless steel A2

This version in stainless steel A2 covers the M 20 thread at 55 mm length. The cylindrical head with 30.0 mm diameter and 20.0 mm height takes an AF 17 hex socket, so no wrench flats are needed on the head.

Benefits

• Size M 20 transmits high clamping forces, and the AF 17 hex socket takes the required tightening torque.
• Dimensions to DIN 912 and ISO 4762, therefore interchangeable with existing M 20 joints.
• Stainless steel A2 needs no additional coating and stays resistant in damp surroundings.
• Head diameter 30.0 mm at 20.0 mm head height to DIN 912, matching a cylindrical counterbore.
• The AF 17 hex socket transmits the tightening torque without wrench flats on the head.

Applications

• Assembly in outdoor areas
• Plants in damp surroundings
• Food and beverage technology
• Water treatment and piping
