Hexagon head screw DIN 933 ISO 4017, full thread, M 8x16, AF 13, plain steel 12.9

The hexagon head screw M 8x16 in plain steel with black finish, property class 12.9 joins components with a thread that reaches almost up to the head as specified in DIN 933. Load bearing thread is therefore available over the full length of 16 mm, which simplifies short clamping lengths and through bolted assemblies. Across the flats the head measures 13 mm at a head height of 5.3 mm.

Benefits

• Thread M 8 almost up to the head to DIN 933 and ISO 4017, load bearing over the length of 16 mm
• Hexagon head with 13 mm across flats to DIN and ISO for open end, ring and socket wrenches
• Head height of 5.3 mm keeps the build height of the joint M 8x16 low
• Plain surface without additional coating, the dimensions follow DIN 933 directly
• Property class 12.9 as the characteristic value for the load capacity of the joint M 8x16
• Short clamping lengths are possible because at 16 mm length no plain shank has to be allowed for

Applications

Machine and plant construction in dry surroundings, jig and tool making, bolting of gearbox and bearing housings, maintenance work on existing equipment.
