Hexagon head screw DIN 933 ISO 4017, full thread, M 4x40, AF 7, stainless steel A2

The hexagon head screw M 4x40 in stainless steel A2 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 40 mm, which simplifies short clamping lengths and through bolted assemblies. Across the flats the head measures 7 mm at a head height of 2.8 mm.

Benefits

• Hexagon head with 7 mm across flats to DIN and ISO for open end, ring and socket wrenches
• Thread M 4 almost up to the head to DIN 933 and ISO 4017, load bearing over the length of 40 mm
• Stainless steel A2 for surroundings with moisture and regular cleaning
• Head height of 2.8 mm keeps the build height of the joint M 4x40 low

Applications

Plants exposed to moisture and regular cleaning, apparatus and vessel construction, interior fitting, mounting of panels and covers.
