Key benefits Prevents fastener loosening: Split spring washers grip under nuts and bolts to resist rotation from vibration and friction, maintaining tight, reliable connections. Distributes load: The washer evens out clamping forces to reduce localized stress on joined parts and protect mating surfaces. Durable in harsh environments: Made from high-quality, corrosion- and rust-resistant metal to extend service life and reduce maintenance. What this product does Compatible with nuts and bolts of the same nominal size to provide a secure lock and consistent load distribution. The split lock design bites into the nut or bolt head and mating surface to help prevent movement and loosening. Ideal where vibration, thermal cycling, or repeated loads threaten fastener integrity. Key features Function: Anti-loosening and load-distribution for bolted connections. Compatibility: Works with nuts and bolts of the same size. Material: High-quality metal with corrosion and rust resistance for long-term performance. Performance: Improves joint stability and reduces the need for retightening. Installation Quick and simple to install with no special tools required. Insert between the fastener and the surface, then tighten manually or with standard tightening equipment. Designed for straightforward retrofitting or use during initial assembly. Typical applications Automotive and transportation: Secure fasteners on engines, suspension components, brackets, and assemblies exposed to vibration. Industrial machinery and equipment: Lock bolts on motors, gearboxes, conveyors, and mounting flanges to maintain alignment and uptime. Building, HVAC, and household equipment: Use on mounting hardware, ductwork, and appliances where vibration or thermal cycling can loosen fasteners. Why choose this washer Provides reliable locking and even load transfer without complicating assembly. Corrosion-resistant construction reduces replacement frequency and maintenance cost. Simple installation and broad compatibility make it a practical solution for both professionals and DIY users.
