Overview

The NSi Industries JSSW8 Stainless Steel Flat Washer is a precision-engineered, Type 18-8 stainless steel washer designed for industrial applications requiring corrosion resistance and mechanical strength. Manufactured to exacting standards, this washer features a 3/8-inch outside diameter (OD) and a 5/32-inch inside diameter (ID), making it compatible with standard 3/8" bolt sizes. The 18-8 grade stainless steel composition provides exceptional resistance to corrosion, chlorides, and sulfides, ensuring long-term reliability in harsh environments such as marine, chemical processing, and outdoor infrastructure projects. This flat washer is ideal for applications where a flush, even surface is required to distribute load and prevent damage to fastened materials. Common uses include construction, automotive assembly, plumbing systems, and electrical installations where non-magnetic properties and durability are critical. The washer's precision flat design ensures consistent performance, reducing the risk of loosening under vibration or dynamic loads. Packaged in a bulk quantity of 100 washers per pack, the JSSW8 is optimized for high-volume industrial use, reducing downtime and streamlining inventory management. The Type 18-8 stainless steel designation is the most common non-magnetic stainless steel fastener grade, offering a balance of strength, formability, and corrosion resistance. Unlike carbon steel washers, this product will not rust or degrade in wet or chemically aggressive environments, making it a cost-effective long-term solution. NSi Industries, a trusted manufacturer in the hardware industry, ensures each washer meets rigorous quality standards for dimensional accuracy and material integrity. Whether used in conjunction with bolts, screws, or threaded rods, the JSSW8 provides a secure, reliable interface that enhances joint integrity and extends the service life of assembled components. For professionals who demand durability without compromising on performance, the JSSW8 is an essential component in any toolkit.
