Hexagon head bolt DIN 931 / ISO 4014, M 10x70, hexagon 17 mm, shank 44 mm, stainless steel A2

Plants that are washed down regularly call for resistant fasteners. This hexagon head bolt M 10x70 to DIN 931 made of stainless steel A2 meets that requirement without any coating. Of the 70 mm total length, 26 mm are threaded and 44 mm stay plain. The hexagon with 17 mm across flats can still be engaged after a long service life.

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.
• Stainless steel A2 stays bright under moisture and wash water, so an additional coating is not needed.
• Plain shank of 44 mm within 70 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

Flange joints in machine building where the 44 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 stainless steel A2.
