This mounting nut fits onto a probe thermocouple or RTD so it can securely mount through the side of a panel or enclosure. Here are the steps for assembling the pieces:

  • Slide the shorter nut onto the probe with the threaded end facing outward
  • Slide on the mounting sleeve
  • Slide the longer nut onto the probe with the long end facing outward
  • Move the pieces to the desired length on the probe and tighten the front and back nuts until secure
