Features

Low-Profile Head
Carriage Bolts are designed with a smooth, low-profile head, which allows for materials to easily pass over their tops without damage. This style of head is also aesthetically pleasing and adds a finished or decorative look to any application.
Greater Load Distribution
Thanks to their large diameter head, Carriage Bolts will distribute the clamping load across a wider area and will resist being pulled through softer building materials such as wood.


Square Neck
Carriage Bolts feature a square neck that prevents the bolt from turning when tightening the nut during installation. The square neck design also helps draw the bolt into softer installation materials, locking the bolt in place, creating a secure bond between the fastened components in your assembly.
