Overview

The NSi Industries LW1745M 3/8" split lock washer is a precision-engineered fastener component designed to prevent loosening from vibration or torque in industrial, automotive, and construction applications. Constructed from high-strength steel with a zinc plating, it provides reliable corrosion resistance and mechanical integrity. The zinc undercoat (u/m) enhances durability and ensures long-term protection against rust and oxidation, even in harsh environments. The 3/8" size ensures compatibility with standard 3/8" fasteners, offering a secure fit for heavy-duty assemblies. Supplied in bulk packaging of 5,000 units, this washer is ideal for large-scale projects requiring consistent, high-volume hardware. NSi Industries, a US-based manufacturer, guarantees consistent quality and performance for critical fastening applications. The split design creates tension between mating surfaces, maintaining clamp load and preventing fastener rotation under dynamic loads. Suitable for use in machinery, structural connections, equipment assemblies, and heavy machinery where vibration resistance is essential. The split configuration distributes pressure evenly, reducing the risk of joint failure in high-stress applications.
