Cup Head Bolt M12 × 400 – Galvanised Steel
This M12 × 400 Cup Head Bolt is made from high-tensile steel and protected with a hot-dip galvanised coating, offering excellent strength, durability, and long-term corrosion resistance. The domed cup head with a square neck prevents rotation during tightening, ensuring a secure, flush fit — ideal for timber construction, decking, fencing, landscaping, and large-scale structural applications.
The metric coarse M12 thread provides strong fastening and easy installation, while the galvanised coating delivers superior protection against rust, abrasion, and exposure to harsh outdoor conditions. Designed for construction, agricultural, and outdoor environments, this bolt provides reliable, long-lasting performance even under demanding conditions.
