Cup Hd Bolt M12 X 300 Gal x 1
Cup Head Bolt M12 × 300 – Galvanised Steel
This M12 × 300 Cup Head Bolt is made from high-tensile steel and coated with a hot-dip galvanised finish, offering superior strength, durability, and corrosion protection for outdoor and structural applications. 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 heavy-duty structural projects.
The metric coarse M12 thread allows for strong engagement and smooth installation, while the galvanised coating provides long-lasting resistance to rust, abrasion, and harsh weather conditions. Designed for construction, agricultural, and outdoor use, this bolt ensures reliable fastening and long service life in demanding environments.
