More About Part Number 320951

These #4 x 1/2" Self-Tapping Screws feature a Flat Undercut 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 B self-tapping screws feature blunt points and spaced threads, making them useful for forming threads in prepunched holes. 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 Undercut Head sits flush with the surface while reducing material displacement, making it useful in thin materials and layered assemblies. A Phillips drive features a cross-shaped recess designed for efficient installation with standard Phillips drivers and power tools.
