Cup Square Bolts

Strong and reliable fixings are essential for timber construction, fencing, and structural installations. Cup Square Bolts, also known as coach bolts, are designed to provide secure fastening where strength, stability, and a neat finish are required. Their smooth domed head offers a clean appearance, while the square neck locks into the material to prevent the bolt from turning as the nut is tightened.

Manufactured from high-quality steel with a corrosion-resistant zinc-plated finish, these bolts are built to withstand demanding applications while delivering long-lasting performance. They are suitable for joining timber sections, securing fencing, assembling wooden structures, and fixing metal components to timber.

Whether you’re completing a new construction project, installing fencing, or carrying out repair work, Cup Square Bolts provide the strength and reliability needed for professional results.

Installation Guidance
