TURBO CLAMP IMPROVEMENT

Spiralock Corp. offers its new V-Band Clamp Nut called Spiralock. Its unique internal thread form withstands extreme turbocharger heat and vibration, while reducing cost, assembly, and warranty issues.  This re-engineered thread form adds a unique 30-degree wedge ramp at the root of the thread which mates with standard 60-degree male thread fasteners. 

  The wedge ramp allows the bolt to spin freely relative to female threads until clamp load is applied.  The crests of the standard male thread form are then drawn tightly against the wedge ramp, eliminating radial clearances and creating a continuous spiral line contact along the entire length of the thread engagement.  This continuous line contact spreads the clamp force more evenly over all engaged threads, improving resistance to vibrational loosening, axial-torsional loading, joint fatigue, and temperature extremes.
