Overview

The NSi Industries JW113 Fender Washer is a precision-engineered steel washer designed for industrial fastening applications requiring corrosion resistance and secure load distribution. Manufactured from cold-rolled steel with a zinc chromate finish, this washer provides superior protection against rust and oxidation in outdoor, marine, and high-moisture environments. With a 1/4-inch inside diameter and 1-inch outside diameter, the JW113 is specifically sized to fit 1/4-inch bolts and screws, making it ideal for automotive bodywork, heavy machinery, and structural assemblies where a larger bearing surface is required to prevent surface damage. The zinc chromate coating meets MIL-C-15074 standards for corrosion resistance, ensuring long-term reliability in applications exposed to salt spray, humidity, or chemical contaminants. Packaged in quantities of 100, this washer is optimized for bulk procurement in manufacturing, maintenance, and repair operations, reducing downtime by ensuring consistent availability. Common applications include securing fenders, brackets, and panels in automotive repair, as well as use in construction equipment, agricultural machinery, and electrical enclosures where vibration resistance and uniform pressure distribution are critical. The washer's flat design and larger outer diameter compared to standard washers distribute clamping force over a wider area, reducing the risk of surface deformation on softer materials like aluminum or fiberglass. NSi Industries, a USA-based manufacturer, produces this washer to tight dimensional tolerances, ensuring consistent fitment with standard 1/4-inch fasteners. The zinc chromate finish provides a durable, yellowish-gold appearance that also serves as a visual indicator of corrosion protection.
