Hexagon head bolt DIN 931 / ISO 4014, M 16x120, hexagon 24 mm, thread length 38 mm, steel 8.8, plain

More highly preloaded joints need a defined shank cross section. This hexagon head bolt M 16x120 to DIN 931 in steel of property class 8.8, plain and black offers 82 mm of plain shank and limits the thread to 38 mm. Tightening takes place on the hexagon with 24 mm across flats at a head height of 10.0 mm. The surface is plain and black.

Advantages

• Dimensions to DIN 931 and ISO 4014, so replacement and repeat orders are unambiguous through the designation M 16x120.
• Plain shank of 82 mm within 120 mm of total length, which places the shear plane in the full shank cross section instead of the thread.
• 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.
• Hexagon head with 24 mm across flats, so the tightening torque can be applied with an ordinary open-ended or ring spanner.
• Head height of 10.0 mm keeps the overall height of the joint low.

Applications

Flange joints in machine building where the 82 mm shank aligns the parts against each other. Bolting of bearing blocks and brackets with a through hole in size M 16. Building of fixtures and clamping plates where the head with 24 mm across flats must stay freely accessible. Releasable joints that are opened several times for maintenance.

Standards and conformity

The bolt is dimensioned to DIN 931 and ISO 4014. The width across flats is 24 mm to DIN 931 and 24 mm to ISO 4014. The material is steel of property class 8.8, plain and black.
