M12 x 260mm Hot Dip Galvanised Cup Head Bolts & Nuts

M12 x 260mm Hot Dip Galvanised Cup Head Bolts & Nuts are built for deep anchoring in large-scale timber construction. With a long 260mm reach and thick 12mm diameter, these bolts provide maximum strength for securing heavy timber components like posts, sleepers, and beams. The hot-dip galvanised finish delivers superior corrosion resistance in outdoor, coastal, or wet environments. A smooth cup head design offers a neat, flush fit with added tamper resistance perfect for structural builds, retaining walls, and external frameworks.
