Our pan head tapping screws work well for a wide range of applications, and the black pan head self tapping screws are no exception. Their pan head design boasts a large bearing surface, so they won’t easily damage thin sheets or soft materials when tightened. The smooth, rounded head looks clean and sleek, making them perfect for exposed installations where appearance counts.
The drive slot is perfectly centered, so tools line up easily and thread stripping is rarely an issue—this is especially true for Phillips and Torx drives. Plus, the sharp pointed tip allows for precise positioning and smooth penetration, fitting seamlessly with thin metal sheets, plastics, wood, fiberboard, and more.
