Hexagon head bolt DIN 931 / ISO 4014, M 6x45, hexagon 10 mm, thread length 18 mm, steel 10.9, plain

Where a bolted joint has to fit exactly, any coating inside the thread gets in the way. This hexagon head bolt M 6x45 to DIN 931 is supplied plain and black and therefore keeps its nominal dimensions. The plain shank of 27 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

• Plain shank of 27 mm within 45 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.
• Property class 10.9, plain and black, suited to more highly preloaded joints in protected indoor positions.
• Head height of 4.0 mm keeps the overall height of the joint low.
• Dimensions to DIN 931 and ISO 4014, so replacement and repeat orders are unambiguous through the designation M 6x45.

Applications

Steelwork and frame structures with through holes for M 6. Mounting of motors, gearboxes and pumps where the plain shank of 27 mm takes the shear load. Assembly of housing covers and panels with a clamping length up to 27 mm. Replacement of damaged standard bolts in size M 6x45.

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 10.9, plain and black.
