A box of 200 high-performance 5.0 x 40mm woodscrews is a robust, medium-duty timber fastener designed for strong wood-to-wood fixings where high shear strength is required in shorter lengths. Featuring a double-countersunk head with self-sinking reaming ribs, deep thread geometry, and a sharp cut tip, it drives cleanly into timber and sheet materials without splitting or requiring pre-drilling in softwoods. Yellow-zinc passivated for corrosion protection and low driving friction, the 5.0mm gauge combined with a 40mm length makes it ideal for securing ironmongery, bracketry, hinges, subflooring, and general timber framing assemblies.
