I get no force indication when pulling a fastner.  Rate it


The load cell attached to the gauge contains mineral oil. This load cell is sealed with lip seals or "o" rings. The seals wear out and cause an oil leak. If the oil is to low, the gauge will not indicate pull force accurately. The seals must be replaced. The assembly must be evacuated, oil filled then calibrated. Please send your load cell to Com-Ten for repair.

I need parts for my fabric lifter foot.  Rate it

Parts, subassemblies and fabric are available. Please contact C-m-Ten Industries with a description of what parts you want.

The digital display is blank on my fastner tester.  Rate it

The batteries are probably dead. Please see your operator’s manual for specific battery replacement instructions. The batteries are inside the digital gauge. You must remove the protective rubber boot from the gauge. Push on the front edge of the boot to push it behind the gauge. Battery access is from the back of the gauge.

I have lost the capstan arms to my tester. What can I do?  Rate it

The thread size of the capstan arms is 5/16-18. You may be able to find bolts long enough to do the job short term. When you get tired of the bolts hurting your hands please call Com-Ten Industries and order two each Com-Ten part number capstan arms.



What do I return for calibration?  Rate it

The gauge cell is the only part that requires calibration. The gauge cell consists of the hydraulic load cell and gauge either analogue or digital. The gauge cell is attached to the tester base with two cap screws. Turn the capstan arms counter clockwise to lower the torque bar as much as possible for screw access. If you turn the tester upside down you will notice the screws through the top of the base. Remove these screws then thread the gauge cell off of the power screw. Sent the gauge cell for calibration. Gauge cells are interchangeable and replaceable. You may wish to keep a spare for emergencies.
