CLAMP The WONDER NUT

The World's Most Techologically Advanced Tension Machine

The CLAMP is a three piece fastener that will directly replace any type of helical nut.

The CLAMP's interlocking surfaces provide pure axial bolt tensioning without the need for an external reaction point.

The CLAMP provides extremely accurate bolt loading as all frictional forces are integral to the controlled CLAMP's surfaces.

The CLAMP is the highest level of bolting optimization. It gives you all of the benefits of the LoaDisc for application where there is little or no side clearance. By replacing the nut with one that turns in itself at a known friction, with no side load or torsion, bolt stretching to the desired bolt load has become reality. For critical applications and the ultimate peace of mind, this is the professional choice.

  • The inner sleeve is connected to the bolt end and is held stationary by the HYTORC machine during operation
  • The outer sleeve, which turns on the washer face, is connected to the inner sleeve by an acme thread (ASME/ANSI B1.5) providing a higher turning friction to the inner sleeve and washer than the outer sleeve
  • When the action force of the HYTORC machine is applied to the outer sleeve and its opposite reaction force to the inner sleeve, the outer sleeve turns at a known coefficient of friction on precision machined surfaces
  • The results in the inner sleeve (and the bolt) rising in a torsion-free, pure axial motion applying pre-calibrated tension to the bolt
  • The hardened washer remains stationary during the entire operation, eliminating facial galling
  • Pure, mechanical bolt tension is provided hands free (even on inverted applications) without the use of bridges, pullers or jack screws, and without relying on bolt relaxation to seat the nut!
  • The CLAMP is rated for temperatures up to 1,000 degree's farenheit (537 degree's celsius)
  • The CLAMP is available for any bolt size (imperial/metric), any thread configuration and upon request, is available in speciality materials to suit the application and environmental conditions

  • Install the CLAMP, set the pump pressure, place the tool and simply push a button on the remote control to achieve unprecedented bolt load accuracy to +5% guaranteed!

The CLAMP is a perfect solution for limited radius applications

Applications set into a pocket or a counter bore situation pose a problem with conventional tooling. Standard drive extensions and machined down compromising the safety of the operator!

The design and mechanics of the CLAMP allow positioning the HYTORC machine away from the conflict area!
