RT-Bolt is the industry leading tool for measuring bolt load accurately under all, including extreme conditions. Designed by globally recognised experts for real world scenarios. RT-Bolt can be incorporated into most bolt sizes and works with permanently installed or removable electronic and manual probes.
RT-Bolt Technology
World Leading Bolt Load Measurement, Accurate Even Under Extreme Conditions
RT-Bolt works accurately under all conditions. Rigourously tested RT-Bolt has been independently verified to be the most accurate tool of it's kind. Extreme temperatues, repeatability, user error, bolt bending, impact and position of nut have all been exhaustively tested.
RT-Bolt uses the bolt itself to measure load accurately by creating an integral pin. Creating a pin inside the bolt ensures the material is consistent. Bolt load can then be accurately measure using an electronic or manual probe measuring the difference in movement between the pin and the body of the bolt.
RT-Bolt, Bolt Load Measurement
- No temperature limits (from cryogenics to 800℃)
- No parts to loosen or degrade
- Protected measurement surfaces
- Accuracy provided by bore guidance

Industry Case Studies
HYTORC USE RT-BOLT FOR KNURLING STUDY PUBLICATION
The Problem:
Hytorc needed a simplified reliable Bolt Load Measurement method that was comparible to well controlled laboratory measuring rods that would work at high temperatures for research. The study was on the impact of Bearing Face Knurling on bold load relaxation at elevated temperatures.
The Consequence:
"The RT-Bolts worked very well! We were very impressed with the repeatability of the measurements. I have spent years...
Integrity Assurance for Offshore Platform Compact Flange Conversion
The Problem:
Compact flanges were used on a NPS 40 gas line on an offshore platform. The compact flange joints proved very difficult to seal during assembly and commissioning. They are also likely to be difficult to maintain, as small imperfections can cause leakage of the seal ring. A back-up plan was formulated that involved using a kamprofile gasket in place of the compact seal ring. This required very accurate joint assembly, in order to ensure that an adequate...
Coke Drum Bottom Deheading Valve Joint Assembly and Monitoring
The Problem:
Coke Drums operate at high temperature and
see extreme cycles of operation every 24 hours. Most sites using delayed cokers have had leakage problems with the joint between the bottom deheading valve and the coke drum or coke drum transition spool.
The Consequence:
Joint leakage can escalate to the point where ignition is possible, requiring the unit to be taken offline to repair the joint. This leads to several days of...
Assembly and Monitoring of High Temperature Heat Exchanger Joints
The Problem:
A refinery had continuous nuisance leakage from a bank of high temperature heat exchangers with 3/4” bolts. Assessment of the joint integrity revealed that an extremely high assembly bolt load (90% of yield) was required in order to ensure good joint integrity.
The Consequence:
Leakage of these joints was problematic for the re nery, requiring shutdown to retighten the joints and, on occasion, shutdown to replace the gaskets...
