Zinc yellow passivated plated wood screws with a self countersinking head. They have deep sharp threads that cut into the wood and divide the fibres rather than simply forcing their way through, and a penetrating tip requiring no pilot hole or pre-drilling. These screws are heat treated to ensure they are hard and resistant to snapping. Lubricated with a wax coating to minimise heat and aid insertion. For trouble free fastening in soft or hard wood, MDF or chipboard. Precision Pozidrive heads. Volume discounts apply to a mix of these items. N.B 100m and 120mm lengths are partial threaded. Supplied in box quantities of 200 or 500.
By increasing the size of the head where it meets the body makes these screws much stronger. This minimises the risk of the head shearing under the final tightening torque.
The tip cuts as it penetrates and the initial portion of the thread engages immediately. The sharp point helps when placing the screw and prevents skating.
After plating, the screws undergo a further coating to reduce friction. Lower friction needs less power, meaning more screws driven on a single battery charge. The thread slices effortlessly through the timber without tearing the fibres, making for a much stronger fixing.
