These #4 x 1/2" Self-Tapping Screws feature a Flat Head with a Phillips Drive and are made from Steel. Self-tapping screws are designed to create mating threads during installation, making them useful for fastening into preformed holes in sheet metal, plastic, and similar materials. Type A self-tapping screws combine a sharp point with closely spaced threads, making them versatile for thin metal and similar materials. They feature a Zinc Finish, which provides reliable corrosion protection for general-purpose indoor and light outdoor applications while remaining a cost-effective choice for everyday fastening needs. The Flat Head features a beveled bearing surface, offering a versatile profile commonly used in sheet metal and general fastening applications. A Phillips drive features a cross-shaped recess designed for efficient installation with standard Phillips drivers and power tools.
