The design of the Carriage Bolt, also known as a Coach Bolt or Fully Threaded Cup Square Hex Bolt, features a domed head or countersunk finish. The uniqueness of this fastener lies in the short square section beneath the head, which serves a critical function. This square section grips into the timber being fastened, preventing the bolt from rotating during tightening, thus ensuring a secure connection. For applications involving metal parts, a rib neck version of the carriage bolt is available, featuring longitudinal ribs for enhanced grip and stability.

Application Areas

The Forgefix Carriage Bolt is predominantly used for fastening timber in various construction scenarios. Its effectiveness makes it a popular choice for:

- Timber joist construction in house building projects.

- Numerous decking applications, ensuring that decks are securely anchored and stable.

- Any woodworking projects where robust and reliable fastening is essential.

Benefits of Zinc Plating

The zinc coating applied to these bolts is important for providing long-lasting protection against oxidation. The coating forms a barrier that helps keep moisture and air away from the underlying metal. Should this barrier become damaged, the properties of zinc allow it to act as a sacrificial anode, preventing the formation of rust that typically afflicts unprotected metals. Unlike iron oxide, which compromises the integrity of the surface, the formation of zinc oxide is beneficial; it can remain intact and serve as a further barrier to oxidation, similar to the protective qualities of the oxide layers found on aluminium and stainless steels.

With a comprehensive range of sizes available, the Forgefix Carriage Bolt and Nut set can accommodate a variety of fastening needs, making it a versatile addition to any toolkit, workshop, or construction site. Whether you are a professional builder or a DIY enthusiast, these bolts provide the reliability and performance necessary for successful timber fastening.
