Hexagon head bolt DIN 931 / ISO 4014, M 10x80, hexagon 17 mm, shank 54 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 10x80 to DIN 931 carries 26 mm of thread and a plain shank of 54 mm that aligns the parts against each other. The hexagon head measures 17 mm across flats and 6.4 mm in height. The material is steel of property class 8.8 with an electroplated zinc coating.

Advantages

• Thread length of 26 mm to DIN 931, sufficient for a nut and a washer in size M 10.
• Plain shank of 54 mm within 80 mm of total length, which places the shear plane in the full shank cross section instead of the thread.
• Head height of 6.4 mm keeps the overall height of the joint low.
• Hexagon head with 17 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

Flange joints in machine building where the 54 mm shank aligns the parts against each other. Bolting of bearing blocks and brackets with a through hole in size M 10. Building of fixtures and clamping plates where the head with 17 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 17 mm to DIN 931 and 16 mm to ISO 4014. The material is steel of property class 8.8 with an electroplated zinc coating.
