Hexagon head bolt DIN 931 / ISO 4014, M 20x200, hexagon 30 mm, thread length 46 mm, steel 8.8, plain

More highly preloaded joints need a defined shank cross section. This hexagon head bolt M 20x200 to DIN 931 in steel of property class 8.8, plain and black offers 154 mm of plain shank and limits the thread to 46 mm. Tightening takes place on the hexagon with 30 mm across flats at a head height of 12.5 mm. The surface is plain and black.

Advantages

• Plain shank of 154 mm within 200 mm of total length, which places the shear plane in the full shank cross section instead of the thread.
• Hexagon head with 30 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 12.5 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 20x200.

Applications

Conveying and plant equipment where joints in size M 20 are undone regularly. Bolting of profile frames and cross beams over a clamping range up to 200 mm. Mounting of guide rails and stops with a fitted hole for the shank. Joints where the width across flats of 30 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 30 mm to DIN 931 and 30 mm to ISO 4014. The material is steel of property class 8.8, plain and black.
