Hexagon head bolt DIN 931 / ISO 4014, M 8x100, hexagon 13 mm, shank 78 mm, stainless steel A4

Plants that are washed down regularly call for resistant fasteners. This hexagon head bolt M 8x100 to DIN 931 made of stainless steel A4 meets that requirement without any coating. Of the 100 mm total length, 22 mm are threaded and 78 mm stay plain. The hexagon with 13 mm across flats can still be engaged after a long service life.

Advantages

• Hexagon head with 13 mm across flats, so the tightening torque can be applied with an ordinary open-ended or ring spanner.
• Plain shank of 78 mm within 100 mm of total length, which places the shear plane in the full shank cross section instead of the thread.
• Thread length of 22 mm to DIN 931, sufficient for a nut and a washer in size M 8.
• Stainless steel A4 also withstands chloride-bearing water, which suits outdoor positions and areas close to cleaning agents.
• Head height of 5.3 mm keeps the overall height of the joint low.
