M12 Carriage Bolt

Our Zinc-Plated Carriage Bolts (also known as coach bolts) are the industry standard for securing timber to timber or timber to metal. Featuring a smooth, domed head and a specialized square neck, these fasteners provide a secure, tamper-resistant finish without the need for a drive recess.

Key Features

• Anti-Rotation Design: The square shoulder beneath the head embeds into timber, preventing the bolt from spinning while the nut is being tightened.

• Safety & Aesthetics: The low-profile "mushroom" head provides a smooth, snag-free surface—ideal for high-traffic areas like decks, railings, and playground equipment.

• Corrosion Protection: Finished with a bright zinc plating to provide a moderate level of resistance against rust and oxidation, making them suitable for indoor or sheltered outdoor projects.

• Secure & Tamper-Resistant: Because the bolt head has no slot or drive, it cannot be loosened or removed from the outside, offering enhanced security for gates and fencing.

   

Common Applications

• Decking & Railings: Creating stable connections for posts and balusters.

• Fencing & Gates: Securing latches and hinges with a clean, decorative finish.

• Furniture Assembly: Building picnic tables, workbenches, and outdoor garden beds.

• Structural Joinery: Fastening heavy timber beams or trusses.
