Bolt Testing












Avoiding bolt failure

Incorrect or inaccurately applied torque can lead to joint separation, joint slippage, flange leakage, structural instability, structural failure and vibration.

Any of the following will affect the required torque:

  • Lubrication (type, quantity, position)
  • Bolts: (type, surface finish, grade, surface coating)
  • Thread (quality, form, fit)
  • Nut (type, grade, fit, finish) 

For peace of mind and confidence in your bolting applications, Christie’s Bolt Testing Service uses a Windows® managed test facility to give you the information to apply the correct torque to your particular application.
