Socket head cap screw DIN 912 / ISO 4762, hex socket AF 3, M 4x20, stainless steel A2
This version in stainless steel A2 covers the M 4 thread at 20 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
- Size M 4 with only 7.0 mm head diameter saves space on tight hole patterns.
- The thread running nearly up to the head uses the full length of 20 mm for engagement.
- Head diameter 7.0 mm at 4.0 mm head height to DIN 912, matching a cylindrical counterbore.
- Stainless steel A2 needs no additional coating and stays resistant in damp surroundings.
- The AF 3 hex socket transmits the tightening torque without wrench flats on the head.
