Hexagon head bolt DIN 931 / ISO 4014, M 14x50, hexagon 22 mm, shank 16 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 14x50 to DIN 931 brings a shank of 16 mm and a thread of 34 mm for that purpose. The head is 8.8 mm high and measures 22 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 34 mm to DIN 931, sufficient for a nut and a washer in size M 14.
• Plain shank of 16 mm within 50 mm of total length, which places the shear plane in the full shank cross section instead of the thread.
• Head height of 8.8 mm keeps the overall height of the joint low.
• Hexagon head with 22 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

Conveying and plant equipment where joints in size M 14 are undone regularly. Bolting of profile frames and cross beams over a clamping range up to 50 mm. Mounting of guide rails and stops with a fitted hole for the shank. Joints where the width across flats of 22 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 22 mm to DIN 931 and 22 mm to ISO 4014. The material is steel of property class 8.8 with an electroplated zinc coating.
