Split Lock Washer (USA), Regular, Heat Treated, Plain (Inch)
USA-made Regular Split Lock Washers that are heat treated with a plain finish are built for dependable performance in demanding fastening applications. The heat-treat process increases hardness and strength, making these washers suitable for use with higher-grade bolts and assemblies exposed to vibration, shock, or fluctuating loads. The plain, uncoated steel finish is ideal for indoor or controlled environments where corrosion protection is not a primary requirement.
Designed with a split-ring profile that generates spring tension when compressed, these washers enhance joint security by increasing friction and helping prevent fastener loosening. Manufactured in the USA for consistent quality and reliability, they are commonly used in machinery, equipment assembly, automotive applications, and industrial maintenance where strong, stable fastening performance is essential.
