MACSIM GALVANISED CUP HEAD BOLT- 12MM

The Macsim Carriage Cup Head Bolt and Nut Galvanised 12mm is designed for secure, tamper-resistant fastening in timber construction and joinery, providing a clean, low-profile finish while firmly locking structural elements together.

Key Features

• Application suitability – Ideal for structural timber, decking, fencing, pergolas, and general joinery where strong, through-bolt fastening is required.
• Design – Cup head with square neck resists turning in the timber, ensuring a neat, smooth head finish and enhanced tamper resistance.
• Material quality – Manufactured from quality steel with precise threading for reliable clamping force and consistent performance.
• Durability – Hot-dip galvanised coating offers robust corrosion resistance, making it suitable for outdoor and exposed environments.
• Installation – Simple to install with a pre-drilled hole; the square shank bites into the timber so you only need tools on the nut side.
• Maintenance – Low-maintenance fastening solution that typically requires only periodic visual inspection in long-term timber structures.
• Versatility – Suitable for use with a wide range of timber sizes and assemblies, from light carpentry to heavier structural applications.
