Hexagon head bolt DIN 931 / ISO 4014, M 16x65, hexagon 24 mm, shank 27 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 16x65 to DIN 931 brings a shank of 27 mm and a thread of 38 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

• Thread length of 38 mm to DIN 931, sufficient for a nut and a washer in size M 16.
• Plain shank of 27 mm within 65 mm of total length, which places the shear plane in the full shank cross section instead of the thread.
• Head height of 10.0 mm keeps the overall height of the joint low.
• Hexagon head with 24 mm across flats, so the tightening torque can be applied with an ordinary open-ended or ring spanner.
• Steel of property class 8.8 with an electroplated zinc coating, so the joint stays releasable in dry and occasionally damp surroundings.

Applications

Fixture building with repeated changeovers in size M 16x65. Bolting of tank and pipe supports in wet areas. Mounting of sheet metal structures where the head height of 10.0 mm is limited. Retrofitting of existing plants using the designation DIN 931.

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.
