Wood Screw — Traditional Tapered, Slotted & Modern
Traditional wood screws have a tapered shank with a sharp gimlet point, designed for partial pre-drilling in solid wood. They differ from modern chipboard or deck screws — the taper shape, partial threading, and slotted head are distinguishing features. Hex-head DIN 571 lag screws are heavy-duty wood-screw variants for structural wood connections.

Frequently Asked Questions
Wood screw vs chipboard screw — which should I use?
For solid hardwood joinery (oak, walnut, hardwood furniture), traditional wood screws with proper pre-drilling are still preferred. For softwood framing, plywood, MDF, and chipboard, modern chipboard screws (with their fully-threaded, sharp-pointed design) are easier and faster to drive. For exterior wood, deck screws are designed specifically for that environment.
