Locking Contact Grounding Washers
6-Prong,Serrated on one side, 6-Prong on the other


A Grounding Washers is a conductive metal gasket primarily designed to ensure a reliable connection between electrical equipment and the earth or ground wire, while also serving functions such as anti-loosening, conductivity, and shielding.

1.Electric Shock Prevention (People Safety)
In the event of equipment leakage current, the washer channels the current safely into the ground, preventing people from receiving an electric shock upon contact with the metal enclosure.
2. Static & Lightning Protection
- Rapidly dissipates static electricity, preventing the breakdown of electronic components and averting fire hazards in flammable or explosive environments.
- Provides a low-impedance path to discharge surges during lightning strikes or overvoltage events, thereby protecting the equipment.
3. Reliable Conductivity (Piercing Oxide Layers)
Features a clawed or serrated structure that, upon tightening, pierces through oxide films, paint, or insulating layers on metal surfaces, ensuring a low-resistance electrical connection between the metal structure and the ground wire.
- Commonly used in: Electrical cabinets, photovoltaic modules, elevators, locomotives, and power distribution boxes.
1. Anti-Loosening & Anti-Slip
Utilizes a disc-shaped or conical structure to generate axial tension once the bolt is tightened, effectively preventing the bolt from loosening due to vibration.
2. Electromagnetic Shielding (EMI)
Used in PCBs, RF equipment, and automotive electronics to suppress electromagnetic interference and enhance signal stability.
3. Potential Stabilization
Provides a zero-potential reference point, ensuring the accuracy of circuit measurements and control operations.
