Hexagon head bolt DIN 931 / ISO 4014, M 6x40, 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 6x40 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 22 mm.

Advantages

• Thread length of 18 mm to DIN 931, sufficient for a nut and a washer in size M 6.
• Plain shank of 22 mm within 40 mm of total length, which places the shear plane in the full shank cross section instead of the thread.
• Head height of 4.0 mm keeps the overall height of the joint low.
• Hexagon head with 10 mm across flats, so the tightening torque can be applied with an ordinary open-ended or ring spanner.
• Stainless steel A2 stays bright under moisture and wash water, so an additional coating is not needed.
