By axially stretching the bolts, the desired preload force is applied directly to the connection, completely torsion-free and without friction losses in the thread. The integration of a mechanical return spring elevates this series to a new level of process speed and operational safety.\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\n\u003ch3 style=\"margin-bottom: 11px;\"\u003e\u003cspan style=\"font-size:11pt\"\u003e\u003cspan style=\"line-height:107%\"\u003e\u003cspan style=\"font-family:Aptos,sans-serif\"\u003eFunctionality and Advantages of Automatic Spring Return\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\n\u003cp style=\"margin-bottom:11px\"\u003e\u003cspan style=\"font-size:11pt\"\u003e\u003cspan style=\"line-height:107%\"\u003e\u003cspan style=\"font-family:Aptos,sans-serif\"\u003eThe use of PSTS bolt tensioners significantly streamlines the assembly process for heavy flange connections and in mechanical engineering.\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp style=\"margin-bottom:11px\"\u003e\u003cspan style=\"font-size:11pt\"\u003e\u003cspan style=\"line-height:107%\"\u003e\u003cspan style=\"font-family:Aptos,sans-serif\"\u003eAfter positioning the tool and building up hydraulic pressure, the bolt is precisely stretched, allowing the nut to be turned without load.
