Washers, as a key functional component of the fastening system, comprehensively enhance the reliability and durability of bolted connections through scientific mechanical correction and interface optimization. Their precise load distribution transforms concentrated stress into uniform pressure, effectively protecting the surfaces of the joined materials. Their unique elastic design compensates for loosening gaps and maintains a stable preload. Insulated variants further block electrochemical corrosion pathways, achieving electrical isolation between materials.
