Describe Carriage Bolts

Known by several names, including round head bolts, coach bolts, or round head square neck bolts, carriage bolts are a necessary part of fastening systems. Their unusual form is a square neck that leads to a dome-shaped, although shallow, head. Most Indian stainless steel carriage bolt manufacturers and suppliers acknowledge the importance of this square neck in keeping the bolt in square-shaped holes.

Defined by their design, these bolts have a lengthy, cylindrical shank as opposed to conventional bolts, whose threads begin just at the neck joint. According to the neck of the bolt, this distinctive design helps to produce durable and strong connections, particularly in wood-to-wood or wood-to-metal components.

The diameter of our carriage bolts varies from 1/4″ to 3/4″ and their length from 3/4″ to 16″. Metric sizes: the diameter varies from m6 to m42 and the lengths from 12mm to 500mm. These bolts are a great option for many applications because of their simplicity of installation and flexibility. They fit securely even in softer materials thanks to the square neck design, which can be fitted into pre-drilled holes with spacers and hex nuts.
