PJM chipboard screw is a self-tapping screw with a thin shaft and coarse threads. Chipboard is made from resin mixed with wood dust or wood chips, so the threads of chipboard screws are designed with proper spacing and angle to grip firmly and prevent withdrawal from this composite material. These screws securely fasten chipboard to chipboard or chipboard to other materials such as natural wood, particle board, Nova pan board, plaster board, and more. PJM chipboard screws are approved for fastening low-, medium-, and high-density chipboard as well as other wooden structures. The main users include furniture manufacturers, interior decorators, carpenters, and similar professionals.
