Professional Applications & Engineering Value
This steel split lock washer addresses critical vibration-induced loosening challenges in heavy machinery, construction equipment, and industrial assemblies. The split lock washer type creates continuous spring tension against both the bearing surface and fastener head, maintaining clamp force under dynamic loads. Engineered with Rockwell C38 hardness, it provides optimal spring characteristics without compromising ductility. The precise 1.663" ID ensures proper seating on 1 5/8" screws, while the generous 2.553" OD distributes load effectively. This industrial washer solution prevents equipment downtime and maintenance costs in applications where vibration resistance is paramount, from manufacturing plants to infrastructure projects.
Specification Summary & Compliance
This split lock washer features precise dimensional specifications including 1.663" internal diameter, 2.553" outer diameter, and 0.389" thickness, manufactured to ASME B18.21.1 standards for consistent performance. The standard split lock washer type maintains proper spring tension and locking action. Environmental compliance includes RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance with current SVHC requirements, ensuring suitability for regulated applications while meeting international environmental standards.
