Hexagon head bolt DIN 931 / ISO 4014, M 12x45, hexagon 19 mm, shank 15 mm, stainless steel A2

Plants that are washed down regularly call for resistant fasteners. This hexagon head bolt M 12x45 to DIN 931 made of stainless steel A2 meets that requirement without any coating. Of the 45 mm total length, 30 mm are threaded and 15 mm stay plain. The hexagon with 19 mm across flats can still be engaged after a long service life.

Advantages

• Thread length of 30 mm to DIN 931, sufficient for a nut and a washer in size M 12.
• Plain shank of 15 mm within 45 mm of total length, which places the shear plane in the full shank cross section instead of the thread.
• Head height of 7.5 mm keeps the overall height of the joint low.
• Hexagon head with 19 mm across flats, so the tightening torque can be applied with an ordinary open-ended or ring spanner.
• Stainless steel A2 stays bright under moisture and wash water, so an additional coating is not needed.

Applications

Flange joints in machine building where the 15 mm shank aligns the parts against each other. Bolting of bearing blocks and brackets with a through hole in size M 12. Building of fixtures and clamping plates where the head with 19 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 19 mm to DIN 931 and 18 mm to ISO 4014. The material is stainless steel A2.
