Professional Applications & Engineering Value
This 1" split lock washer delivers critical vibration damping in demanding industrial applications where mechanical stability is paramount. The high-strength steel construction with Rockwell C38 hardness maintains consistent spring pressure under dynamic loads, preventing catastrophic fastener failure in machinery, heavy equipment, and structural assemblies. The split lock washer type design creates continuous outward pressure that counters rotational forces, making it ideal for vibration-resistant applications in manufacturing plants, automotive systems, and construction equipment. The precise 0.25" thickness and standardized dimensions ensure reliable performance in repetitive assembly operations while meeting rigorous industrial washer requirements for long-term service life.
Specification Summary & Compliance
Manufactured to ASME B18.21.1 specifications with precise inch system dimensions: 1.024" ID, 1.478" OD, and 0.25" thickness. This standard split lock washer maintains dimensional accuracy for consistent performance with 1" fasteners. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets. The Rockwell C38 hardness rating confirms optimal material properties for reliable locking performance in industrial applications.
