Overview

The NSi Industries JBWSS38 Conical Washer (SKU: JBWSS38) is a precision-engineered stainless steel fastener designed for industrial applications requiring vibration resistance and secure load distribution. Manufactured from 18-8 grade stainless steel, this washer delivers superior corrosion resistance and mechanical strength, making it ideal for harsh environments, including marine, chemical processing, and outdoor infrastructure projects. Key specifications include a 3/8-inch bolt size compatibility, a 3/4-inch outside diameter (OD), and a 7/16-inch inside diameter (ID). The conical design ensures optimal load distribution across the contact surface, reducing the risk of loosening under dynamic loads or vibration—a critical feature for machinery, automotive, and construction applications. This washer eliminates the need for countersunk holes when used with flat or oval head screws, providing a clean, flush finish while maintaining structural integrity. Packaged in quantities of 100, the JBWSS38 is optimized for bulk industrial use, ensuring consistent performance and reliability in high-volume applications. Compatible with standard 3/8-inch bolts and screws, the JBWSS38 is a versatile solution for engineers, contractors, and maintenance professionals seeking durable, corrosion-resistant washers for critical fastening systems. Trust NSi Industries for fasteners that meet the demands of rigorous industrial environments.
