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

Secure large timber connections with strong, lasting hold and a neat, flush finish. These cup head bolts and nuts are sized for substantial joints, with a 260mm reach and 12mm diameter to anchor deep into timber assemblies.

The hot-dip galvanised coating delivers enhanced corrosion resistance, making them ideal for outdoor, coastal, or damp environments and helping hardware stay protected over time.

A smooth cup head delivers a clean appearance and added tamper resistance for structural uses such as posts, sleepers, beams, retaining walls, and external frameworks.
