Split Lock Washer, Thru Hardened, Heat Treat, Zinc Yellow (Inch)
Thru Hardened Split Lock Washers with a Zinc Yellow finish are engineered for high-strength fastening applications where superior locking performance and enhanced corrosion resistance are required. The thru-hardening and heat-treat process significantly increases the washer’s strength, making it suitable for use with higher-grade bolts and assemblies subjected to heavy vibration or dynamic loads.
The split, spring-tension design helps prevent fastener loosening by increasing friction within the joint, while the yellow zinc plating provides a durable protective coating and improved visibility during installation. These washers are ideal for automotive, industrial machinery, structural connections, and demanding maintenance applications requiring long-lasting, reliable locking performance.
