Overview

The NSi Industries JLWX7SS 5/16 External Tooth Lock Washer is a precision-engineered fastener designed for applications requiring vibration resistance and corrosion protection. Manufactured from 410 stainless steel, this lock washer provides superior durability in industrial environments where exposure to moisture, chemicals, or temperature fluctuations is common. The external tooth design bites into mating surfaces, creating a secure grip that resists loosening under dynamic loads. With a 5/16-inch size, it is compatible with standard bolt and screw assemblies used in automotive, machinery, construction, and equipment manufacturing. Unlike plain washers, the external teeth distribute load pressure and prevent rotation, ensuring long-term joint integrity. The 410 stainless steel composition offers a balance of hardness and corrosion resistance, outperforming carbon steel in harsh conditions while maintaining cost efficiency compared to higher-grade alloys. Ideal for securing panels, brackets, and structural components, this lock washer meets industrial quality standards for reliability and repeatable performance.
