Hexagon head bolt DIN 931 / ISO 4014, M 10x90, hexagon 17 mm, shank 64 mm, steel 10.9, zinc-plated

In machine and fixture building the hexagon head bolt with shank is the standard fastener for drilled flanges. This version M 10x90 to DIN 931 carries 26 mm of thread and a plain shank of 64 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 10.9 with an electroplated zinc coating.

Advantages

• Head height of 6.4 mm keeps the overall height of the joint low.
• Thread length of 26 mm to DIN 931, sufficient for a nut and a washer in size M 10.
• Property class 10.9 in a zinc-plated version, which provides a more highly preloadable bolt with corrosion protection.
• Plain shank of 64 mm within 90 mm of total length, which places the shear plane in the full shank cross section instead of the thread.
• Hexagon head with 17 mm across flats, so the tightening torque can be applied with an ordinary open-ended or ring spanner.

Applications

Steelwork and frame structures with through holes for M 10. Mounting of motors, gearboxes and pumps where the plain shank of 64 mm takes the shear load. Assembly of housing covers and panels with a clamping length up to 64 mm. Replacement of damaged standard bolts in size M 10x90.

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 10.9 with an electroplated zinc coating.
