The Extra Heavy lockwasher is a heavy-duty bolt split lockwasher that serves as a popular alternative to the AREA/AREMA specification track washer in railroad and industrial applications. It delivers greater clamp force than a standard split lockwasher, making it suitable for demanding fastening applications where the full AREMA spec is not required.
Commonly used in railroad track maintenance, bridge work, and heavy structural connections. In stock at Kimes Steel & Rail — contact us for quantity pricing.
