Extension springs with turnable bolt

Our series of extension springs features an advanced design that both ensures a specific tensile force when extended to a precise length but also maximizes the use of the extension spring's full potential without the risk of breaking. This specially developed model with a turnable bolt is perfect for efficiently utilizing the extension spring's extendable length (Ln). Our extension springs with turnable bolts can either be mounted directly into a threaded hole or equipped with a custom end fitting, providing flexibility and adaptability across various applications.
