Carriage bolt DIN 603 with square neck, M 10x40, zinc-plated steel 3.6 / 4.6

The carriage bolt joins two parts with a flat head that hardly protrudes and locks itself against turning through the square neck. In addition the sheet lists a head height of 5.0 mm. Its rating is a head diameter of 24 mm.

Benefits

• Thread M 10 at a length of 40 mm, the thread length is 26 mm.
• Flat head 24 mm across and only 5.0 mm high, so the bearing area stays large and the head hardly protrudes.
• Square 10 mm under the head, it engages in the hole and holds the bolt while it is tightened.
• The matching hexagon nut has a width across flats of 17 mm to DIN and 16 mm to ISO 8677.
• Made of zinc-plated steel 3.6 / 4.6 to DIN 603.

Applications

On a joint that is accessible from one side only, the 10 mm square holds the bolt while the nut is tightened.

Standards and conformity

The widths across flats to DIN and to ISO 8677 are given separately because they can differ from M 10 upwards.
