Hexagon head bolt DIN 931 / ISO 4014, M 12x60, hexagon 19 mm, shank 30 mm, steel 8.8, zinc-plated

In machine and fixture building the hexagon head bolt with shank is the standard fastener for drilled flanges. This version M 12x60 to DIN 931 carries 30 mm of thread and a plain shank of 30 mm that aligns the parts against each other. The hexagon head measures 19 mm across flats and 7.5 mm in height. The material is steel of property class 8.8 with an electroplated zinc coating.

Advantages

• Thread length of 30 mm to DIN 931, sufficient for a nut and a washer in size M 12.
• Plain shank of 30 mm within 60 mm of total length, which places the shear plane in the full shank cross section instead of the thread.
• Head height of 7.5 mm keeps the overall height of the joint low.
• Hexagon head with 19 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

Steelwork and frame structures with through holes for M 12. Mounting of motors, gearboxes and pumps where the plain shank of 30 mm takes the shear load. Assembly of housing covers and panels with a clamping length up to 30 mm. Replacement of damaged standard bolts in size M 12x60.

Standards and conformity

The bolt is dimensioned to DIN 931 and ISO 4014. The width across flats is 19 mm to DIN 931 and 18 mm to ISO 4014. The material is steel of property class 8.8 with an electroplated zinc coating.
