Hexagon head bolt DIN 931 / ISO 4014, M 14x70, hexagon 22 mm, thread length 34 mm, steel 8.8, plain

More highly preloaded joints need a defined shank cross section. This hexagon head bolt M 14x70 to DIN 931 in steel of property class 8.8, plain and black offers 36 mm of plain shank and limits the thread to 34 mm. Tightening takes place on the hexagon with 22 mm across flats at a head height of 8.8 mm. The surface is plain and black.

Advantages

• Steel of property class 8.8, left plain and black, which means no coating thickness on the thread and an exact fit in the hole.
• Width across flats of 22 mm to DIN 931 and 22 mm to ISO 4014, both figures are stated and therefore known before assembly.
• Plain shank of 36 mm within 70 mm of total length, which places the shear plane in the full shank cross section instead of the thread.
• Thread length of 34 mm to DIN 931, sufficient for a nut and a washer in size M 14.

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 70 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 steel of property class 8.8, plain and black.
