Thread-Cutting Screws for PlasticThese screws cut threads into drilled holes as they’re turned, so they require less driving torque and cause less stress on material than thread-forming screws. Also known as Type BT and Type 25 screws, they have coarse threads that grip soft plastic. They're 410 stainless steel, which is strong, wear resistant, and mildly chemical resistant. Length is measured from under the head.
