Overview

The NSi Industries 1090-7 Reducing Washer is a precision-engineered galvanized steel component designed for industrial applications requiring a secure transition between two differently sized fasteners or components. This washer features a 4-inch outer diameter and a 2.5-inch inner diameter, allowing it to bridge connections between larger and smaller hardware in mechanical assemblies, construction projects, and manufacturing systems. Constructed from galvanized steel, it provides superior corrosion resistance, making it ideal for use in outdoor, marine, or chemically aggressive environments where rust and degradation are common concerns. The washer meets industry standards for load-bearing capacity and dimensional accuracy, ensuring reliable performance in critical applications. Commonly used in structural framing, piping systems, and machinery assemblies, the 1090-7 reduces the need for custom fabrication by offering a standard solution for size transitions. Its durable coating and robust design eliminate the risk of galvanic corrosion when paired with compatible fasteners, extending the lifespan of connected assemblies. NSi Industries, a U.S.-based manufacturer, produces this washer to exacting tolerances, ensuring consistent fit and function across all installations.
