Chipboard screws, also named particleboard screws, are self-tapping screws with thin shafts and coarse threads. They are made of carbon steel or stainless steel and then galvanized. Chipboard screws of different lengths can be used in a variety of applications. They are created to fasten low, medium, and high-density chipboard. Many chipboard screws are self-tapping, so there is no need to drill holes in advance.☆ Be widely used in the structural steel industry, metal building industry, mechanical equipment industry, automobile industry, etc. Ideal for chipboards and wood, they are often used for cabinetry and for flooring. ☆ Common length (around 4cm) chipboard screws are often used to join chipboard flooring to regular wood joists. ☆ Small chipboard screws (around 1.5cm) can be used to fasten hinges to chipboard cabinetry. Long (around 13cm) chipboard screws can be used to fasten chipboard to chipboard when making cabinets.(1). DESCRIPTIONS: The Galvanised Chipboard Screw has a coarse thread and a fine shank to maximize grip into chipboard, MDF, and other soft timbers. The head has nibs which help to remove the chipboard particles when countersinking. The galvanized coating is suitable for most outdoor applications. chipboard screw or particleboard screw is a self-tapping screw with a thin shaft and coarse threads. Chipboard is made up of resin and wood dust or wood chips, so chipboard screws are made to grip this composite material and to resist withdrawing. The screws solidly fasten chipboard to chipboard or chipboard to other materials such as natural wood. Chipboard screws come in a variety of lengths and can be used to fasten chipboard in a variety of applications. Average length chipboard screws are often used to join chipboard flooring to regular wood joists. Smaller screws may be used to fasten hinges to chipboard cabinetry. Very long screws may be used to butt chipboard to chipboard when making cabinets. Average screws are 1.5 inches (around 4 cm), small screws are usually ½ inches (around 1.5 cm), longer screws are 5 inches (around 13 cm). Different shapes and materials of chipboard screws are common as well. The most common screws are made out of zinc, yellow zinc, brass, or black oxide. Popular heads are either pan, flat, or bugle, and popular gauges are 8 and 10. Screws may have Phillips or square (Robertson) screw drives. (2).MULTI HEAD: Cutting ribs help the head countersink. Screw head ribs help reduce the thread being stripped when fixings hinges etc. Deeper recess for stronger bit hold. (3).4CUT POINT: No Splitting even when working close to the edge. No pre-drilling required even in hardwoods. Screw point takes immediate hold. (4).GROUND SERRATIONS: Reduces driving in torque. Hard Synthetic coating for easy driving. Ultimate holding power.
