Just like our high-torque worm gear clamps, Mishimoto’s Constant Tension Worm Gear Clamps are an effective solution to a wide range of clamping needs. Where this 3.27” – 4.13” (83mm – 105mm) constant tension worm gear clamp excels, however, is in high-temperature applications. The spring on the adjustment bolt allows the clamp to exert continuous pressure through a wide range of temperatures to ensure your parts stay clamped as strong as the day you installed them
