Socket head cap screw DIN 912 / ISO 4762, hex socket AF 17, M 20x80, stainless steel A4

This socket head cap screw to DIN 912 joins components with the M 20 thread over a length of 80 mm. It is tightened through the AF 17 hex socket, and the head measures 30.0 mm in diameter at 20.0 mm height. The specified material is stainless steel A4.

Benefits

• Stainless steel A4 resists chloride-bearing surroundings as well and needs no coating.
• Head diameter 30.0 mm at 20.0 mm head height to DIN 912, matching a cylindrical counterbore.
• Dimensions to DIN 912 and ISO 4762, therefore interchangeable with existing M 20 joints.
• Size M 20 transmits high clamping forces, and the AF 17 hex socket takes the required tightening torque.
• A thread length of at least 52 mm within 80 mm overall length leaves a plain shank section.

Applications

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