Torque vs. Preload Comparison
Compressor bolting applications can be specially challenging. You need a bolting solution that can be installed and removed safely and quickly. On the below details you will see examples of bolting problems solved with NMTG Tensioner nut. We look forward to working with you on your critical bolting applications.
NMTG Tensioner nut are designed as direct replacements for standard / conventional hex bolt. They can be threaded onto a new or existing bolt, stud, threaded rod or shaft. With tensioner nut, bolting is fast, safe, easy and accurate - only hand tools are required.
Product Name: Tensioner Nuts / Jam Nuts
Model Name: TNG
The wrench used to remove the existing piston nut is connected to an overhead crane (safety hazard). This results in the piston rod rotating in the jig, which must be clamped together.
Piston end tensioner nut are tightened and loosened with only a hand torque wrench. Proper tightness is achieved and rotation on the piston rod is eliminated. No special tools are required for piston end NMTG tensioner nuts and the piston can be installed and removed in place. There is no need to clamp the piston rod if it is out of the compressor.

Standard hex nuts on compressor rod-to-crosshead connections are almost impossible to tighten in this limited space. Typically sledge hammers or cranes are used, but these are unsafe for the workers and not very efficient or accurate.
NMTG tensioner Nut makes the installation of piston rods easy. Because only hand tools are required for installation and removal, the dangers associated with the crane are eliminated.
