The Zenith M12 x 100mm hot dip galvanised cup head bolt and nut is a 4.6 grade steel fixing built for outdoor projects where corrosion resistance counts. The hot dip galvanised coating shields the steel, making the bolt suited to retaining walls, gates, fences, pergolas and outdoor furniture.
The low-profile cup head sits flush for a neat finish, while the square neck beneath the head grips timber so the bolt does not spin as the nut is tightened. The coarse thread provides strong holding power across timber-to-timber and metal-to-timber fixings.
