Carriage bolt DIN 603 with square neck, M 8x25, zinc-plated steel 3.6 / 4.6

Once installed, the carriage bolt joins two parts with a flat head that hardly protrudes and locks itself against turning through the square neck. The data also state a head height of 4.5 mm. This version comes with thread M 8 and length 25 mm.

Benefits

• Thread M 8 at a length of 25 mm, the thread length is up to approximately the head.
• Flat head 20 mm across and only 4.5 mm high, so the bearing area stays large and the head hardly protrudes.
• Square 8 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 13 mm to DIN and 13 mm to ISO 8677.
• Made of zinc-plated steel 3.6 / 4.6 to DIN 603.

Applications

In timber and steel construction the M 8x25 bolt pulls the plate against the timber and the flat head stays almost flush.

Standards and conformity

The widths across flats to DIN and to ISO 8677 are given separately because they can differ from M 8 upwards.
