Custom DIN 603 Cup Head Square Neck Carriage Bolts

Cup Head Square Neck Bolts / Carriage Bolts

Use the current DIN 603 cup-head square-neck form, or withdrawn ISO 8677 legacy geometry where the old drawing requires it, as the starting point for a custom carriage bolt. Specify head profile and diameter, square-neck width and height, mating-hole engagement, thread and grip lengths, material, property class, coating, tolerances and inspection.

DIN 603 remains an active standard family. ISO 8677 was withdrawn in 2019 but is still used on legacy drawings, stock descriptions and industry enquiries, so it remains a valid historical cross-reference rather than a current replacement. Do not substitute small-head ISO 8678 or inch-series ASME B18.5 geometry. The square neck and mating feature must be designed together to prevent rotation.
