Hexagon head bolt DIN 931 / ISO 4014, M 14x55, hexagon 22 mm, shank 21 mm, stainless steel A2

Outdoors and in wet areas large bolts must still come loose after years. This hexagon head bolt M 14x55 to DIN 931 made of stainless steel A2 stays resistant without a coating. The plain shank measures 21 mm and the thread 34 mm. The hexagon head has 22 mm across flats and a height of 8.8 mm.

Advantages

• Head height of 8.8 mm keeps the overall height of the joint low.
• Thread length of 34 mm to DIN 931, sufficient for a nut and a washer in size M 14.
• Stainless steel A2 stays bright under moisture and wash water, so an additional coating is not needed.
• Plain shank of 21 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 22 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 14 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 22 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 22 mm to DIN 931 and 22 mm to ISO 4014. The material is stainless steel A2.
