    Carriage Bolts

    What are Carriage Bolts?

    Carriage Bolts are a robust and durable fastener solution, featuring a domed head, which can help prevent loosening from one side. Carriage Bolts also feature a square section underneath their head, which makes them self-locking when used within a square hole. These components are manufactured with a minimum thread length, Full Thread Carriage Bolts are also available.

    Bolt Materials

    In addition to A2 Stainless Steel, Carriage Bolts are available in A4, also called Marine Grade Stainless Steel. Additional features such as Chemical Blackening and Thread Locking Patches are also available for Accu's Stainless Steel Carriage Bolt range. For alternative material types of bolts in this range, please contact our team.

    Metric Bolts

    Metric Carriage Bolts are manufactured according to DIN 603. Diameters of between M5 and M16 are available as standard, with lengths of between 25mm and 300mm also available. Head Diameter sizes range from 12.45mm to 37.2mm.
