Overview

The NSi Industries JSSW15 stainless steel flat washer is a precision-engineered SAE-grade fastener designed for industrial applications requiring corrosion resistance and mechanical strength. Made from 18-8 grade stainless steel (AISI 304 equivalent), this washer resists rust, corrosion, and oxidation in harsh environments, including marine, chemical processing, food and beverage, pharmaceutical, and outdoor industrial settings. Its 18-8 composition ensures high tensile strength, durability, and resistance to high temperatures, making it suitable for demanding applications. With an outside diameter of 1-1/16 inches (27.0 mm) and an inside diameter of 17/32 inches (13.5 mm), it fits standard 1/2-inch bolts (12.7 mm nominal), ensuring compatibility with common hardware in mechanical assemblies, automotive systems, construction projects, and heavy machinery. The washer’s precise dimensions provide a snug fit, reducing the risk of misalignment and ensuring consistent performance in critical fastening applications. The JSSW15 is supplied in a 100-piece bulk packaging, ideal for high-volume industrial use. This bulk packaging reduces procurement time, simplifies inventory management, and streamlines assembly processes, making it a cost-effective solution for large-scale projects. The washer’s robust construction and accurate sizing deliver consistent load distribution and vibration resistance, enhancing the reliability and longevity of fastened joints. NSi Industries, a US-based manufacturer, produces this washer to meet rigorous quality standards for durability and accuracy in professional fastening solutions. The JSSW15 is a reliable choice for engineers, contractors, and maintenance professionals seeking a high-performance, corrosion-resistant washer for critical applications.
