The Zenith M10 x 150mm Hot Dipped Galvanised Black Cup Head Bolt and Nut is a long fastener built for heavy outdoor timber connections. The low-profile dome cup head gives a flush, tidy finish, while the square neck under the head grips the timber so the bolt won't spin as you tighten the nut.
The generous 150mm length suits thick joints in retaining walls, sleepers, heavy gates, pergola posts and decking. The hot dipped galvanised coating delivers strong corrosion protection for weather-exposed timber-to-timber and metal-to-timber connections, and a matching nut is included.
