No.7 (3.9mm) x 19mm Phillips Pan Head Tek Screws (DIN 7504NH) - Bright Zinc Plated Steel Phillips Pan Head Self Drilling Tek Screws feature a shallow domed head and a Phillips Drive. The self-drilling tip operates in the same fashion as a drill bit, which eradicates the need for a pre-drilled pilot hole. Once the initial hole has been created, Self-Drilling Tek Screws will then tap their own threads into the fastened material, much in the same way as a self-tapping screw. This makes Self-Drilling Tek Screws extremely versatile as they can be used with a wide variety of materials such as wood, metal, and plastics, and therefore across a broad range of industries. These Phillips Pan Head Self Drilling Tek Screws are made from Bright Zinc Plated Steel which provides a level of corrosion and oxidation resistance as well as a bright finish.
