Hexagon head bolt DIN 931 / ISO 4014, M 14x90, hexagon 22 mm, shank 56 mm, stainless steel A4

Outdoors and in wet areas large bolts must still come loose after years. This hexagon head bolt M 14x90 to DIN 931 made of stainless steel A4 stays resistant without a coating. The plain shank measures 56 mm and the thread 34 mm. The hexagon head has 22 mm across flats and a height of 8.8 mm.

Advantages

• Hexagon head with 22 mm across flats, so the tightening torque can be applied with an ordinary open-ended or ring spanner.
• Plain shank of 56 mm within 90 mm of total length, which places the shear plane in the full shank cross section instead of the thread.
• Thread length of 34 mm to DIN 931, sufficient for a nut and a washer in size M 14.
• Stainless steel A4 also withstands chloride-bearing water, which suits outdoor positions and areas close to cleaning agents.
• Head height of 8.8 mm keeps the overall height of the joint low.

Applications

Fixture building with repeated changeovers in size M 14x90. Bolting of tank and pipe supports in wet areas. Mounting of sheet metal structures where the head height of 8.8 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 22 mm to DIN 931 and 22 mm to ISO 4014. The material is stainless steel A4.
