Socket head cap screw DIN 912 / ISO 4762, hex socket AF 17, M 20x55, stainless steel A4
Where the screw head has to disappear flush into a counterbore, this DIN 912 socket head cap screw works with M 20 and 55 mm length. Head diameter 30.0 mm and head height 20.0 mm define the counterbore, and the tool engages in the AF 17 hex socket. The material is stainless steel A4.
Benefits
- The AF 17 hex socket transmits the tightening torque without wrench flats on the head.
- Size M 20 transmits high clamping forces, and the AF 17 hex socket takes the required tightening torque.
- Head diameter 30.0 mm at 20.0 mm head height to DIN 912, matching a cylindrical counterbore.
- Stainless steel A4 resists chloride-bearing surroundings as well and needs no coating.
