Hexagon head bolt DIN 931 / ISO 4014, M 14x140, hexagon 22 mm, shank 100 mm, steel 8.8, zinc-plated

Large flanges and steelwork transfer their loads through a small number of heavy bolts. This hexagon head bolt M 14x140 to DIN 931 brings a shank of 100 mm and a thread of 40 mm for that purpose. The head is 8.8 mm high and measures 22 mm across flats, so a torque wrench has a safe grip. The material is steel of property class 8.8 with an electroplated zinc coating.

Advantages

• Hexagon head with 22 mm across flats, so the tightening torque can be applied with an ordinary open-ended or ring spanner.
• Plain shank of 100 mm within 140 mm of total length, which places the shear plane in the full shank cross section instead of the thread.
• Thread length of 40 mm to DIN 931, sufficient for a nut and a washer in size M 14.
• Steel of property class 8.8 with an electroplated zinc coating, so the joint stays releasable in dry and occasionally damp surroundings.
• Head height of 8.8 mm keeps the overall height of the joint low.

Applications

Flange joints in machine building where the 100 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 8.8 with an electroplated zinc coating.
