Hexagon head bolt DIN 931 / ISO 4014, M 16x180, hexagon 24 mm, shank 136 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 16x180 to DIN 931 brings a shank of 136 mm and a thread of 44 mm for that purpose. The head is 10.0 mm high and measures 24 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 24 mm across flats, so the tightening torque can be applied with an ordinary open-ended or ring spanner.
• Plain shank of 136 mm within 180 mm of total length, which places the shear plane in the full shank cross section instead of the thread.
• Thread length of 44 mm to DIN 931, sufficient for a nut and a washer in size M 16.
• 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 10.0 mm keeps the overall height of the joint low.

Applications

Steelwork and frame structures with through holes for M 16. Mounting of motors, gearboxes and pumps where the plain shank of 136 mm takes the shear load. Assembly of housing covers and panels with a clamping length up to 136 mm. Replacement of damaged standard bolts in size M 16x180.

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 with an electroplated zinc coating.
