Hexagon head bolt DIN 931 / ISO 4014, M 5x65, hexagon 8 mm, thread length 16 mm, stainless steel A2

In damp surroundings the material decides whether a joint can still be undone years later. This hexagon head bolt M 5x65 to DIN 931 is made of stainless steel A2 and needs no additional protective coating. The head is 3.5 mm high and is gripped across flats of 8 mm. The thread runs over 16 mm and the plain shank measures 49 mm.

Advantages

• Head height of 3.5 mm keeps the overall height of the joint low.
• Thread length of 16 mm to DIN 931, sufficient for a nut and a washer in size M 5.
• Stainless steel A2 stays bright under moisture and wash water, so an additional coating is not needed.
• Plain shank of 49 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 8 mm across flats, so the tightening torque can be applied with an ordinary open-ended or ring spanner.

Applications

Steelwork and frame structures with through holes for M 5. Mounting of motors, gearboxes and pumps where the plain shank of 49 mm takes the shear load. Assembly of housing covers and panels with a clamping length up to 49 mm. Replacement of damaged standard bolts in size M 5x65.

Standards and conformity

The bolt is dimensioned to DIN 931 and ISO 4014. The width across flats is 8 mm to DIN 931 and 8 mm to ISO 4014. The material is stainless steel A2.
