This M12 spring washer features a single coil, square section design with a bright zinc plated finish to aid resistance against corrosion in sheltered environments. It is commonly used within nut and bolt assemblies to help maintain joint integrity, especially when components are exposed to vibration or movement.
On site, the spring washer is placed between the nut and the material being secured. It provides a locking action that supports fastener security, making it suitable for tasks involving metalwork, machinery, or fixtures where prevention of loosening is required.
