Torro® Worm Gear Clamps with Integrated Springs add an automatic self-adjusting constant tension to the 9 or 12mm asymmetric worm drive clamp. Tightening the screw loads the spring with enough clamping force to ensure a long-lasting automatic re-tensioning effect, even in very low temperatures. The self-adjusting radial clamping force achieved makes these ideal for applications under extreme temperature changes (e. g. charged air) or for the retention of hoses with a tendency of "creeping" (hose relaxation). They are particularly suited to connecting cooling and heating hoses.
