Product Introduction: Carriage bolts, also known as coach bolts, are a type of fastener that features a smooth domed head and a square section under the head. They are designed to be tightened by hand or with a wrench and are commonly used in wood and some types of metal applications where a flush, clean finish is desired.

When selecting carriage bolts, it is essential to consider the specific requirements of your application, including the material, size, thread pitch of the bolt, load capacity, and environmental factors. For high-stress applications, go for bolts made of hardened steel or heat-treated alloy with a higher strength rating. To protect against rust or corrosion, opt for stainless steel or galvanized bolts with a zinc or chrome coating. When selecting the size and thread pitch, consult the engineering specifications or guidelines relevant to your project.
The main difference is that carriage bolts have a smooth, unthreaded shank and a distinctive square or hexagonal head, while regular bolts typically have a threaded shank and a rounded head.
The size of the carriage bolt should be chosen based on the thickness of the material being fastened and the amount of load the bolt will need to bear. It’s also important to consider the diameter of the hole that can be drilled and the space available for the bolt head.
