Hexagon head bolt DIN 931 / ISO 4014, M 6x55, hexagon 10 mm, thread length 18 mm, stainless steel A4

In damp surroundings the material decides whether a joint can still be undone years later. This hexagon head bolt M 6x55 to DIN 931 is made of stainless steel A4 and needs no additional protective coating. The head is 4.0 mm high and is gripped across flats of 10 mm. The thread runs over 18 mm and the plain shank measures 37 mm.

Advantages

• Head height of 4.0 mm keeps the overall height of the joint low.
• Thread length of 18 mm to DIN 931, sufficient for a nut and a washer in size M 6.
• Stainless steel A4 also withstands chloride-bearing water, which suits outdoor positions and areas close to cleaning agents.
• Plain shank of 37 mm within 55 mm of total length, which places the shear plane in the full shank cross section instead of the thread.
• Hexagon head with 10 mm across flats, so the tightening torque can be applied with an ordinary open-ended or ring spanner.

Applications

Conveying and plant equipment where joints in size M 6 are undone regularly. Bolting of profile frames and cross beams over a clamping range up to 55 mm. Mounting of guide rails and stops with a fitted hole for the shank. Joints where the width across flats of 10 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 10 mm to DIN 931 and 10 mm to ISO 4014. The material is stainless steel A4.
