Hexagon head bolt DIN 931 / ISO 4014, M 20x140, hexagon 30 mm, shank 88 mm, stainless steel A4

Outdoors and in wet areas large bolts must still come loose after years. This hexagon head bolt M 20x140 to DIN 931 made of stainless steel A4 stays resistant without a coating. The plain shank measures 88 mm and the thread 52 mm. The hexagon head has 30 mm across flats and a height of 12.5 mm.

Advantages

• Thread length of 52 mm to DIN 931, sufficient for a nut and a washer in size M 20.
• Plain shank of 88 mm within 140 mm of total length, which places the shear plane in the full shank cross section instead of the thread.
• Head height of 12.5 mm keeps the overall height of the joint low.
• Hexagon head with 30 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.
