Hexagon head bolt DIN 931 / ISO 4014, M 5x60, hexagon 8 mm, thread length 16 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 5x60 to DIN 931 is supplied plain and black and therefore keeps its nominal dimensions. The plain shank of 44 mm centres the part while the 16 mm of thread carry the preload. Tightening is done on the hexagon with 8 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 8 mm to DIN 931 and 8 mm to ISO 4014, both figures are stated and therefore known before assembly.
• Plain shank of 44 mm within 60 mm of total length, which places the shear plane in the full shank cross section instead of the thread.
• Thread length of 16 mm to DIN 931, sufficient for a nut and a washer in size M 5.

Applications

Steelwork and frame structures with through holes for M 5. Mounting of motors, gearboxes and pumps where the plain shank of 44 mm takes the shear load. Assembly of housing covers and panels with a clamping length up to 44 mm. Replacement of damaged standard bolts in size M 5x60.

Standards and conformity

The bolt is dimensioned to DIN 931 and ISO 4014. The width across flats is 8 mm to DIN 931 and 8 mm to ISO 4014. The material is steel of property class 8.8, plain and black.
