These TIMCO Drywall Fine Thread Bugle Head Black Screws are designed for securing plasterboard to wall and ceiling track systems. They are suitable for materials up to 0.6 mm thick and are manufactured from C10-18 steel with surface hardness to prevent torque under load. The screws feature a 3.5 x 50 mm size, fine thread, bugle head, and black finish, and are plated in zinc or black phosphate to help resist corrosion. They are fully threaded up to 50 mm, with partial threading thereafter, and are tested to relevant standards for sharpness, thread, and performance.
