Overview

The NSi Industries JW121SS Stainless Steel Fender Washer is a precision-engineered industrial fastener designed for applications requiring superior load distribution and corrosion resistance. This Type 18-8 stainless steel washer features a 1/2-inch inside diameter (ID) and a 2-inch outside diameter (OD), making it ideal for use with 1/2-inch bolts and screws. The fender washer design provides an expanded surface area that distributes mechanical loads across a larger surface, reducing stress on fastened materials and preventing damage to softer substrates like wood or thin sheet metal. Manufactured from 18-8 grade stainless steel, the JW121SS offers excellent resistance to corrosion, oxidation, and harsh environmental conditions, including exposure to moisture, chemicals, and temperature fluctuations. This makes it suitable for use in marine, automotive, construction, machinery, and industrial environments where reliability and longevity are critical. The 18-8 grade (AISI 304 equivalent) ensures high tensile strength and durability, while the fender washer profile enhances stability and load-bearing capacity in critical assemblies. Packaged in a convenient 50-piece quantity, the JW121SS is optimized for bulk industrial use, reducing procurement frequency and streamlining inventory management. NSi Industries, a trusted name in mechanical fasteners, ensures consistent quality and dimensional accuracy. This product is ideal for engineers, contractors, and maintenance professionals seeking a dependable solution for applications involving heavy loads, vibration, or corrosive atmospheres. Compatible with standard 1/2-inch fasteners, the JW121SS is a versatile and essential component for any industrial or construction project requiring robust, long-lasting washers.
