ForgeFix Carriage Bolts M12 x 200mm Zinc Plated Bag 5

These Forgefix Carriage Bolts are expertly designed for timber-to-timber connections, making them an essential choice for construction and decking applications. Known for their durability and ease of use, these zinc-plated bolts come equipped with a hex nut and feature a fully threaded length of up to 100mm. The bolts are also referred to as 'Cup Square Hex Bolts' owing to their unique design, where a square section beneath the dome head effectively prevents rotation during tightening.

Design and Specifications

Crafted to adhere to strict DIN 603 and DIN 934 standards, these bolts boast a robust construction suitable for various timber fastening tasks. The domed or countersunk head coupled with the square section under it ensures a secure grip into the timber, thereby preventing any movement or loosening over time. For applications requiring additional grip, rib neck variants of the carriage bolt are available. These alternative designs include longitudinal ribs that provide enhanced stability when fastening to metal parts.

Applications

Primarily, these carriage bolts are used for fastening timber to timber, making them indispensable in timber joist construction for houses and extensive decking projects. Their ability to grip securely into wooden surfaces ensures lasting strength and stability in structures, which is paramount for both safety and durability.

Protective Coating

One of the standout features of these carriage bolts is their zinc coating, which serves as a protective barrier against oxidation. This zinc plating not only enhances the aesthetic appearance of the bolts but also significantly extends their lifespan by preventing corrosion. If the zinc layer becomes damaged, it acts as a sacrificial anode, providing ongoing protection by forming zinc oxide, a non-corrosive compound that further reduces the risk of rust. In contrast to other metals that may corrode, such as iron, zinc ensures that the integrity of the fastened surfaces remains intact.

Summary

Overall, Forgefix Carriage Bolts combine durability, functionality, and versatility, making them an ideal choice for contractors and DIY enthusiasts alike. Their secure fastening capabilities, coupled with zinc plating for corrosion resistance, ensure that they meet the demands of modern construction projects. Available in a comprehensive range of sizes, these bolts are designed to meet a variety of fastening needs, providing reliable performance wherever timber structures are required.
