Description & Specs

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.
