Hexagon head screw DIN 933 ISO 4017, full thread, M 16x55, AF 24, plain steel 8.8

The 55 mm long hexagon head screw M 16x55 transfers load through a thread that reaches almost up to the head. The material plain steel with black finish, property class 8.8 determines the load capacity and the behaviour towards moisture. Across the flats the head measures 24 mm, its height comes to 10.0 mm.

Benefits

• Plain surface without additional coating, the dimensions follow DIN 933 directly
• Thread M 16 almost up to the head to DIN 933 and ISO 4017, load bearing over the length of 55 mm
• Short clamping lengths are possible because at 55 mm length no plain shank has to be allowed for
• Hexagon head with 24 mm across flats to DIN and ISO for open end, ring and socket wrenches
• Property class 8.8 as the characteristic value for the load capacity of the joint M 16x55
