Constructed with a durable zinc plating, Brighton-Bests Phillips Pan-Head Self-Drill Screws offer a basic level of corrosion resistance suited for indoor or low-exposure environments. The pan-head profile provides a wide bearing surface and is paired with a Phillips drive to reduce the chance of cam-out during installation. Their 1-1/2 inch length and 1/4 inch diameter offer reliable performance in applications that require consistent grip and alignment through overlapping metal surfaces. These are a go-to fastener when precision and efficiency matter.
