Double-headed Rivet

Our double-headed rivets feature two different diameters: one step for positioning and the other for riveting. This design precisely controls riveting depth, making it ideal for applications where alignment is critical. Common uses include car door hinges, seat adjusters, engine mounts, and precision machine shafts.

A car seat recliner customer approached us needing a single rivet to serve as both a shaft and a stop. Standard rivets could not meet this requirement. We designed a product for him: the larger step positioned on the bracket, while the smaller step riveted to the moving part. A single installation performed both functions. This customer now orders 2 million pieces annually.

Our tool design capabilities are strong. Multi-step and special-shaped parts are our specialty. We support custom orders from drawings-you provide the idea, and we make it a reality.

For our double-headed rivets, step height tolerance is ±0.05 mm, step diameter tolerance is ±0.03 mm, and step concentricity is within 0.02 mm. High-precision cold heading machines form the steps in a single operation, eliminating the need for secondary machining. This ensures high strength and accuracy while maintaining safety. Each batch is tested for these critical dimensions, resulting in a reliable rivet that performs consistently.
