More About Part Number 392963

These 4-40 x 3/8" SEMS Screws feature a Hex Head with a Slotted 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. External Tooth Washer SEMS Screws use a lockwasher with outward-facing teeth that provide aggressive surface engagement and strong resistance to loosening under vibration. 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. A Slotted drive features a single straight groove that accommodates a flathead screwdriver for simple manual installation.
