This custom stamped spring shim is made of high-quality 304 stainless steel, precision formed with 4 mounting lugs, central hole and 2mm mounting holes for secure installation. The 0.6mm thickness balances flexibility and structural strength, while the passivated surface treatment ensures excellent corrosion resistance without additional coatings. It is designed to provide consistent preload, eliminate assembly gaps, prevent loosening and absorb minor vibrations in various assemblies. We offer full OEM & custom services to tailor dimensions, hole patterns, thickness and material grades to match your exact design requirements.
