New Star Industries manufactures spring washers to IS 3063-72, in sizes from M3 to M36, engineered to maintain load and prevent bolted joints from loosening under vibration. Available in Zinc Phosphate, Manganese Phosphate, Zinc Electroplating, and ZAC coatings for automotive, machinery, and industrial assemblies.
A spring washer is a split, helically-formed ring rather than a flat disc. When compressed under the bolt head or nut, it acts like a coiled spring, continuously pushing back against the joint. This keeps the fastener under axial tension even if the joint experiences slight relaxation from vibration, thermal cycling, or minor settling — the washer takes up the small movement that would otherwise let a nut back off over time.
Every spring washer we produce conforms to IS 3063-72, which governs the dimensions, split-ring geometry, and spring characteristics required for reliable anti-loosening performance. Manufactured in sizes from M3 to M36, we supply the full range from small precision assemblies to heavy industrial fastening applications.
Spring washers from New Star Industries are used wherever a bolted joint is exposed to vibration or cyclic load and cannot be regularly re-torqued — automotive engine and chassis assemblies, industrial machinery, and general structural fastening where maintaining consistent clamp load over time matters as much as the initial tightening.
Beyond our standard range, New Star Industries manufactures spring washers and all other fastener types as per customer specification, including custom sizes and coatings. Share your drawing with our team, and we'll manufacture to your exact requirement.
