New Star Industries is a specialized Front Spring Bolts Manufacturer in India, producing heavy-duty bolts for suspension systems in commercial vehicles. Our front spring bolts are available in diameters from M16 to M24 (5/8″ to 1″) with lengths up to 500 mm and are manufactured in grades 10.9 and 12.9. These bolts are produced as per customer drawings to meet specific load and performance requirements. Designed to withstand high stress, vibration, and dynamic loads, our front spring bolts ensure stability, safety, and long service life in automotive suspension applications.
As a specialized Front Spring Bolts Manufacturer in India, New Star Industries produces heavy-duty suspension bolts built to survive the punishing, repetitive stress that commercial vehicle suspension systems see every day. A front spring bolt isn't just holding parts together — it's the pivot point that lets the leaf spring flex under load, mile after mile, load after load, without working loose or fatiguing prematurely.
Unlike a structural bolt that's tightened once and left in a fixed joint, a front spring bolt operates as a pivot under constant dynamic loading — every bump, brake, and turn puts it through repeated shear and fatigue stress. That's why we manufacture front spring bolts in grade 10.9 and 12.9 as standard, and produce every batch as per the customer's own drawing so the bolt is matched precisely to the suspension design it's going into.
✓ High Fatigue Resistance: Manufactured in grades 10.9 and 12.9 to withstand the repeated flexing and dynamic loading that a leaf spring pivot point experiences over the vehicle's service life.
✓ Heavy-Duty Sizing: Produced in diameters from M16 to M24 (5/8″ to 1″) and lengths up to 500 mm, covering the range typically specified for commercial vehicle and heavy transport suspension assemblies.
✓ Built to Customer Drawing: Every front spring bolt is manufactured as per the customer's own specification, ensuring correct fit, shank length, and thread engagement for the exact suspension design in use.
✓ Vibration and Shock Tolerance: Designed to maintain clamp integrity under the continuous vibration and shock loading typical of commercial vehicle chassis and suspension systems.
✓ Consistent, Reliable Batches: Manufactured under controlled processes so that every bolt in a production run performs identically — critical for suspension components where a single weak bolt can compromise vehicle safety.
Front spring bolts from New Star Industries are used in the front leaf spring suspension assemblies of commercial trucks, buses, trailers, and other heavy vehicles, where they act as the pivot connecting the spring eye to the chassis hanger bracket. Their strength and fatigue resistance make them equally suited to OEM production lines and aftermarket suspension component supply.
Since front spring bolts are almost always application-specific, New Star Industries manufactures them strictly as per customer drawing — matching diameter, length, grade, and thread specification to your exact suspension design. Share your drawing with our team, and we'll manufacture to your precise requirement.
