Hexagon head bolt DIN 931 / ISO 4014, M 6x90, hexagon 10 mm, thread length 18 mm, stainless steel A2

In damp surroundings the material decides whether a joint can still be undone years later. This hexagon head bolt M 6x90 to DIN 931 is made of stainless steel A2 and needs no additional protective coating. The head is 4.0 mm high and is gripped across flats of 10 mm. The thread runs over 18 mm and the plain shank measures 72 mm.

Advantages

• Hexagon head with 10 mm across flats, so the tightening torque can be applied with an ordinary open-ended or ring spanner.
• Plain shank of 72 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 18 mm to DIN 931, sufficient for a nut and a washer in size M 6.
• Stainless steel A2 stays bright under moisture and wash water, so an additional coating is not needed.
• Head height of 4.0 mm keeps the overall height of the joint low.

Applications

Fixture building with repeated changeovers in size M 6x90. Bolting of tank and pipe supports in wet areas. Mounting of sheet metal structures where the head height of 4.0 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 10 mm to DIN 931 and 10 mm to ISO 4014. The material is stainless steel A2.
