A box of 200 high-performance 4.0 x 30mm woodscrews is a general-purpose timber fastening fixings set designed for rapid driving, high pull-out resistance, and secure wood-to-wood or hardware attachment. Featuring a double-countersunk head with reaming ribs, deep thread geometry, and a sharp self-drilling slash point, these screws minimize timber splitting without requiring prior pre-drilling in softwoods. Yellow-zinc coated or lubricated for low driving torque, the 30mm length is ideal for joining thin timber sections, securing ironmongery, attaching sheet materials, and general site joinery.
