Carriage Bolt & Nut ZP M6 x 75mm Bag 10

These Forgefix Carriage Bolts are specifically designed for securely joining timber components, making them an essential choice for various construction applications. Constructed with a zinc plating, these bolts not only provide corrosion resistance but also enhance durability by preventing oxidation. This zinc coating creates a protective barrier that prolongs the lifespan of the bolts, ensuring reliable performance even in challenging environments.

Product Overview

Forgefix Carriage Bolts, also referred to as Cup Square Hex Bolts or Coach Bolts, feature a distinctive design that integrates a domed or countersunk head with a square neck beneath. This unique square section is engineered to grip into the timber being fastened, effectively preventing rotation during installation when the accompanying hex nut is tightened. With a fully threaded length of 100mm, these bolts allow for versatile fastening options and ensure a snug fit in various timber applications.

Applications

These carriage bolts are predominantly used for fastening timber to timber, making them ideal for timber joist construction in house building and decking projects. Their strength and reliable grip make them suitable for a wide range of applications, from constructing wooden frameworks to securing deck boards. The combination of a square neck and a fully threaded shaft provides excellent clamping force, ensuring that the materials remain securely joined over time.

Design Features

The design of the Forgefix Carriage Bolt incorporates several key features that enhance its performance. The rib neck variant, for instance, includes longitudinal ribs instead of a square neck, which helps grip metal parts being fixed. This versatility makes the carriage bolt suitable for both timber and metal applications. The combination of a secure fastening mechanism and durable construction makes these bolts a reliable choice for professionals and DIY enthusiasts alike.

# Advantages of Zinc Coating

The zinc plating not only provides a protective layer against moisture and environmental factors but also acts as a sacrificial anode. This means that if the zinc barrier is damaged, it will corrode first, thus protecting the underlying metal from rust and degradation. Additionally, the formation of zinc oxide creates a fine white dust that acts as a barrier to further oxidation, enhancing the longevity of the bolt. The efficiency of this protective mechanism is comparable to the natural oxide layers on aluminium and stainless steels, ensuring that these bolts remain strong and effective over time.

In summary, Forgefix Carriage Bolts are an excellent choice for anyone looking to achieve strong, durable, and corrosion-resistant timber-to-timber connections. With their thoughtful design and robust materials, they meet the rigorous demands of modern construction while ensuring ease of use.
