Hexagon head bolt DIN 931 / ISO 4014, M 8x65, hexagon 13 mm, thread length 22 mm, stainless steel A4

Plants that are washed down regularly call for resistant fasteners. This hexagon head bolt M 8x65 to DIN 931 made of stainless steel A4 meets that requirement without any coating. Of the 65 mm total length, 22 mm are threaded and 43 mm stay plain. The hexagon with 13 mm across flats can still be engaged after a long service life.

Advantages

• Head height of 5.3 mm keeps the overall height of the joint low.
• 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.
• Plain shank of 43 mm within 65 mm of total length, which places the shear plane in the full shank cross section instead of the thread.
• Hexagon head with 13 mm across flats, so the tightening torque can be applied with an ordinary open-ended or ring spanner.

Applications

Fixture building with repeated changeovers in size M 8x65. Bolting of tank and pipe supports in wet areas. Mounting of sheet metal structures where the head height of 5.3 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 13 mm to DIN 931 and 13 mm to ISO 4014. The material is stainless steel A4.
