Hexagon head bolt DIN 931 / ISO 4014, M 8x35, hexagon 13 mm, thread length 22 mm, steel 8.8, plain

A fitted joint lives from the shank, not from the thread. This hexagon head bolt M 8x35 to DIN 931 provides a plain shank of 13 mm over its 35 mm of length and moves the thread to the last 22 mm. The shear plane therefore lies in the full shank cross section. The head is 5.3 mm high and is tightened across flats of 13 mm. The bolt is made of steel of property class 8.8, plain and black.

Advantages

• Plain shank of 13 mm within 35 mm of total length, which places the shear plane in the full shank cross section instead of the thread.
• Hexagon head with 13 mm across flats, so the tightening torque can be applied with an ordinary open-ended or ring spanner.
• 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.
• Head height of 5.3 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 8x35.

Applications

Conveying and plant equipment where joints in size M 8 are undone regularly. Bolting of profile frames and cross beams over a clamping range up to 35 mm. Mounting of guide rails and stops with a fitted hole for the shank. Joints where the width across flats of 13 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 13 mm to DIN 931 and 13 mm to ISO 4014. The material is steel of property class 8.8, plain and black.
