Hexagon head bolt DIN 931 / ISO 4014, M 12x180, hexagon 19 mm, shank 144 mm, stainless steel A4

Plants that are washed down regularly call for resistant fasteners. This hexagon head bolt M 12x180 to DIN 931 made of stainless steel A4 meets that requirement without any coating. Of the 180 mm total length, 36 mm are threaded and 144 mm stay plain. The hexagon with 19 mm across flats can still be engaged after a long service life.

Advantages

• Thread length of 36 mm to DIN 931, sufficient for a nut and a washer in size M 12.
• Plain shank of 144 mm within 180 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 A4 also withstands chloride-bearing water, which suits outdoor positions and areas close to cleaning agents.

Applications

Fixture building with repeated changeovers in size M 12x180. Bolting of tank and pipe supports in wet areas. Mounting of sheet metal structures where the head height of 7.5 mm is limited. Retrofitting of existing plants using the designation DIN 931.

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 A4.
