Our most popular thread-forming screws for plastic also resist rust. Thread them directly into molded or cast holes—no inserts needed. Screws won’t crack or distort material when fastening enclosures, panels, and other plastic components. The Phillips drive handles enough torque to keep drivers from slipping and the rounded head creates a finished look.
Length is measured from under the head.
18-8 Stainless Steel—The choice for wet and outdoor environments, these screws resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.
Round—The sharply angled threads drive into plastic with less force and a lower risk of cracking than other tapping screws. The base of the threads is recessed to bite deep into material and hold tight. You can reuse these screws a few times without stripping the threads. They're comparable to PT screws.
