Hexagon head bolt DIN 931 / ISO 4014, M 8x40, hexagon 13 mm, thread length 22 mm, stainless steel A4

Plants that are washed down regularly call for resistant fasteners. This hexagon head bolt M 8x40 to DIN 931 made of stainless steel A4 meets that requirement without any coating. Of the 40 mm total length, 22 mm are threaded and 18 mm stay plain. The hexagon with 13 mm across flats can still be engaged after a long service life.

Advantages

• Thread length of 22 mm to DIN 931, sufficient for a nut and a washer in size M 8.
• Plain shank of 18 mm within 40 mm of total length, which places the shear plane in the full shank cross section instead of the thread.
• Head height of 5.3 mm keeps the overall height of the joint low.
• Hexagon head with 13 mm across flats, so the tightening torque can be applied with an ordinary open-ended or ring spanner.
• Stainless steel A4 also withstands chloride-bearing water, which suits outdoor positions and areas close to cleaning agents.

Applications

Conveying and plant equipment where joints in size M 8 are undone regularly. Bolting of profile frames and cross beams over a clamping range up to 40 mm. Mounting of guide rails and stops with a fitted hole for the shank. Joints where the width across flats of 13 mm has to match the available tools.

Standards and conformity

The bolt is dimensioned to DIN 931 and ISO 4014. The width across flats is 13 mm to DIN 931 and 13 mm to ISO 4014. The material is stainless steel A4.
