Overview

The NSi Industries JSLW8 5/16" split lock washer is a medium-duty Type 18-8 stainless steel locking washer designed to prevent bolted joints from loosening under vibration or dynamic loads. Manufactured from corrosion-resistant 18-8 stainless steel (AISI 304 equivalent), this washer maintains mechanical integrity in harsh environments including marine, chemical, and outdoor applications. The split design creates a spring action that increases tension on the joint, ensuring a secure connection even when subjected to repeated stress cycles. With a 5/16" inner diameter and standard medium split profile, it fits common 5/16" bolts and screws used in industrial machinery, automotive assemblies, and structural connections. Supplied in a 100-piece pack for bulk industrial use, the JSLW8 offers a cost-effective solution for maintenance operations and assembly lines requiring reliable vibration resistance. Compatible with standard hardware and distributed by Gross Automation, this washer meets industrial quality standards for mechanical fasteners.
