Carriage bolt DIN 603 with square neck, M 6x30, 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. This version is listed with thread M 6 and length 30 mm. Its rating is a head diameter of 16 mm.

Benefits

• Thread M 6 at a length of 30 mm, the thread length is 18 mm.
• Flat head 16 mm across and only 3.5 mm high, so the bearing area stays large and the head hardly protrudes.
• Square 6 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 10 mm to DIN and 10 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 6 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 6 upwards.
