About Star Washers
Star washers, also known as internal-tooth lock washers, feature sharp radial teeth punched around the inner or outer diameter that dig into the bolt head and mating surface when tightened. This mechanical bite resists rotational loosening under vibration while also cutting through paint, oxide, or plating to create a low-resistance electrical bonding path — making star washers a preferred choice wherever grounding or electrical continuity matters alongside mechanical locking. Unlike spring washers that rely on axial spring force alone, the tooth geometry of a star washer provides both a locking action and a scraping/bonding action in a single component. They are widely used in electrical panel assembly, grounding and earthing connections, automotive and appliance assembly, and general machinery where a compact, self-locking washer is needed. Stellar Global Supplies stocks star washers in a full range of sizes ex-Pune with pan-India delivery.
