The Zenith M6 x 25mm hot dipped galvanised coach screw is a 4.6 grade steel fastener for fastening timber to timber and metal to timber. The hex head drives with a spanner or socket for increased clamping pressure, while the gimlet point helps it bite and penetrate timber.
The hot dipped galvanised finish gives this coach screw corrosion resistance for outdoor timber work such as fences, gates, pergolas and outdoor furniture. Matching M6 hot dipped galvanised washers are available to seat under the head.
