More About Part Number 356039

These 4-40 x 1/2" SEMS Screws feature a Pan Head with a Phillips Drive and are made from Steel. SEMS Screws are pre-assembled screw-and-washer fasteners designed to simplify installation, reduce handling time, and help prevent lost components during assembly. Internal Tooth Washer SEMS Screws use a lockwasher with inward-facing teeth that bite into the mating surface, helping resist loosening while fitting within a smaller outside diameter. They feature a Black Oxide Finish, which provides mild corrosion resistance and a dark matte appearance and is commonly used in indoor or lightly protected applications. The Pan Head features a slightly rounded top with a flat 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.
