Socket head cap screw DIN 912 / ISO 4762, hex socket AF 3, M 4x25, stainless steel A2

This version in stainless steel A2 covers the M 4 thread at 25 mm length. The cylindrical head with 7.0 mm diameter and 4.0 mm height takes an AF 3 hex socket, so no wrench flats are needed on the head.

Benefits

• Stainless steel A2 needs no additional coating and stays resistant in damp surroundings.
• Head diameter 7.0 mm at 4.0 mm head height to DIN 912, matching a cylindrical counterbore.
• Dimensions to DIN 912 and ISO 4762, therefore interchangeable with existing M 4 joints.
• The thread running nearly up to the head uses the full length of 25 mm for engagement.
• The AF 3 hex socket transmits the tightening torque without wrench flats on the head.

Applications

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