Product Overview
An Industrial Washer is a thin, flat disc with a central hole designed to be placed between a fastener and the mounting surface. Washers help distribute the clamping force evenly, reduce wear on surfaces, prevent loosening caused by vibration, and improve the overall performance of bolted joints. Depending on the application, different types of washers are available, including Flat Washers, Spring Washers, Lock Washers, Plain Washers, Fender Washers, and Square Washers.
At Moksh Tubes & Fittings LLP, we manufacture high-quality Industrial Washers using premium-grade materials and precision machining processes. Our washers are available in a wide range of sizes, thicknesses, and material grades to meet the requirements of industrial, construction, and engineering applications.
Industrial Washers are precision-engineered fastening components used with bolts, nuts, and threaded rods to distribute load, protect surfaces, reduce vibration, and ensure secure fastening.
