Carriage Bolts: The Unsung Heroes of Construction and Assembly

In the world of hardware and construction, the seemingly simple carriage bolt plays a crucial role in a wide range of applications. Known for its unique design and robust performance, the carriage bolt is often the unsung hero behind many successful construction projects and assemblies. In this blog, we'll explore what carriage bolts are, their key features, benefits, and various applications.

What Are Carriage Bolts?

Carriage bolts, also known as coach bolts, are a type of fastener characterized by their round, smooth heads and square or rectangular necks. These bolts are designed to be used with a nut or directly into a pre-tapped hole. The round head provides a clean finish and is often used where a smooth surface is desired.

Key Features:

- Round Head: The head of the carriage bolt is rounded, providing a clean, finished appearance and preventing snagging.

- Square Neck: The neck of the bolt is square or rectangular, which prevents the bolt from turning when the nut is tightened.

- Threaded Shaft: The shaft of the bolt is fully threaded, allowing for secure fastening into nuts or pre-tapped holes.

- Material: Typically made from steel, stainless steel, or other durable materials to ensure strength and longevity.
