Hexagon head bolt DIN 931 / ISO 4014, M 6x80, hexagon 10 mm, thread length 18 mm, steel 8.8, plain

Where a bolted joint has to fit exactly, any coating inside the thread gets in the way. This hexagon head bolt M 6x80 to DIN 931 is supplied plain and black and therefore keeps its nominal dimensions. The plain shank of 62 mm centres the part while the 18 mm of thread carry the preload. Tightening is done on the hexagon with 10 mm across flats.

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 10 mm to DIN 931 and 10 mm to ISO 4014, both figures are stated and therefore known before assembly.
• Plain shank of 62 mm within 80 mm of total length, which places the shear plane in the full shank cross section instead of the thread.
• Thread length of 18 mm to DIN 931, sufficient for a nut and a washer in size M 6.

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 80 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 steel of property class 8.8, plain and black.
