Hexagon head bolt DIN 931 / ISO 4014, M 12x45, hexagon 19 mm, shank 15 mm, stainless steel A4
Plants that are washed down regularly call for resistant fasteners. This hexagon head bolt M 12x45 to DIN 931 made of stainless steel A4 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 A4 also withstands chloride-bearing water, which suits outdoor positions and areas close to cleaning agents.
