Hexagon head bolt DIN 931 / ISO 4014, M 16x110, hexagon 24 mm, shank 72 mm, steel 10.9, zinc-plated

Large flanges and steelwork transfer their loads through a small number of heavy bolts. This hexagon head bolt M 16x110 to DIN 931 brings a shank of 72 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 10.9 with an electroplated zinc coating.

Advantages

• Head height of 10.0 mm keeps the overall height of the joint low.
• Thread length of 38 mm to DIN 931, sufficient for a nut and a washer in size M 16.
• Property class 10.9 in a zinc-plated version, which provides a more highly preloadable bolt with corrosion protection.
• Plain shank of 72 mm within 110 mm of total length, which places the shear plane in the full shank cross section instead of the thread.
• Hexagon head with 24 mm across flats, so the tightening torque can be applied with an ordinary open-ended or ring spanner.

Applications

Flange joints in machine building where the 72 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 10.9 with an electroplated zinc coating.
