Square Heavy Black Spring Washers are manufactured for applications that require a more robust locking washer compared to standard spring washers. The square heavy profile provides increased strength and resistance under load, helping to maintain bolt tension and reduce the risk of loosening caused by vibration, movement, or repeated stress.
These washers are commonly used in heavy-duty fastening environments such as machinery assembly, steel fabrication, automotive work, agricultural equipment, construction, and general industrial maintenance. The black finish gives the washer a strong industrial appearance while making it suitable for applications where a non-bright finish is preferred.
Designed to sit beneath the bolt head or nut, the spring action helps create additional tension in the assembly, improving fastening reliability in demanding conditions.
