Chipboard Screws
Measure across the outside of the thread - not the shank - to get the gauge (an 8g screw measures about 4.2mm). Screw gauges have a wider tolerance than bolts, so treat it as a close match rather than exact. Then measure the length - countersunk timber screws are measured overall, head included.
Every product page carries a Screw Gauge and TPI chart for its range - every gauge links straight to the product. Rule of thumb for timber: coarse threads for softwood and framing, fine threads for hardwood.
Chipboard screws are countersunk, sharp-point screws designed for engineered board - chipboard, particleboard, MDF, flooring and cabinetry. The twin-thread (two intertwined threads) drives fast and grips hard in the loose-fibred core of board products where a standard wood screw would strip.
Chipboard screws are also listed under our Furniture Fasteners category - the same product, browseable in both places.
GRADES AND MATERIALS
Stocked in zinc-plated carbon steel for clean interior cabinetry and flooring work, with yellow zinc on some lines. For wet or exterior use, choose a coated or stainless timber screw instead.
DRIVE AND INSTALLATION
Phillips or Pozi drive. The sharp point starts without a pilot in most board; near an edge, pre-drill a small pilot to stop the board blowing out. Countersunk head pulls flush into the board face.
SIZE AND THREAD
Gauges 6g to 10g, lengths 12mm to 75mm. Twin-thread coarse profile for grip in board. Choose a length that holds in the receiving panel without breaking through the back face.
