Hexagon head bolt DIN 931 / ISO 4014, M 12x100, hexagon 19 mm, shank 70 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 12x100 to DIN 931 carries 30 mm of thread and a plain shank of 70 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

• Head height of 7.5 mm keeps the overall height of the joint low.
• Thread length of 30 mm to DIN 931, sufficient for a nut and a washer in size M 12.
• Steel of property class 8.8 with an electroplated zinc coating, so the joint stays releasable in dry and occasionally damp surroundings.
• Plain shank of 70 mm within 100 mm of total length, which places the shear plane in the full shank cross section instead of the thread.
• Hexagon head with 19 mm across flats, so the tightening torque can be applied with an ordinary open-ended or ring spanner.

Applications

Conveying and plant equipment where joints in size M 12 are undone regularly. Bolting of profile frames and cross beams over a clamping range up to 100 mm. Mounting of guide rails and stops with a fitted hole for the shank. Joints where the width across flats of 19 mm has to match the available tools.

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.
