M16 x 360mm Hot Dip Galvanised Cup Head Bolts & Nuts

M16 x 360mm Hot Dip Galvanised Cup Head Bolts & Nuts are built for deep, heavy-duty timber fastening in large-scale construction projects. With a substantial 360mm length and strong 16mm diameter, these bolts are perfect for securing thick posts, beams, and timber structures where maximum holding power is required. The hot-dip galvanised coating offers superior rust and corrosion resistance, making them ideal for outdoor and coastal installations. The rounded cup head ensures a clean, low-profile finish that adds strength and security to any structural timber connection.
