Hexagon head bolt DIN 931 / ISO 4014, M 14x140, hexagon 22 mm, shank 106 mm, steel 10.9, plain

More highly preloaded joints need a defined shank cross section. This hexagon head bolt M 14x140 to DIN 931 in steel of property class 10.9, plain and black offers 106 mm of plain shank and limits the thread to 34 mm. Tightening takes place on the hexagon with 22 mm across flats at a head height of 8.8 mm. The surface is plain and black.

Advantages

• Plain shank of 106 mm within 140 mm of total length, which places the shear plane in the full shank cross section instead of the thread.
• Hexagon head with 22 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 8.8 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 14x140.

Applications

Flange joints in machine building where the 106 mm shank aligns the parts against each other. Bolting of bearing blocks and brackets with a through hole in size M 14. Building of fixtures and clamping plates where the head with 22 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 22 mm to DIN 931 and 22 mm to ISO 4014. The material is steel of property class 10.9, plain and black.
