  • Durable Steel Construction: Manufactured from robust steel, ensuring longevity and consistent performance in harsh workshop and industrial environments.
  • Flush Installation: Designed to sit flush with the material surface after proper installation, creating a clean finish and preventing interference with mating components.
  • High Pull-Out Resistance: The T-shaped head and embedded prongs work together to distribute load effectively and maximize resistance against tensile forces.

Applications

The Mo-Clamp 840505 T-nut is ideal for a wide range of professional fastening tasks. In automotive repair, it can be used for securing interior panels, custom fabrication projects, or mounting aftermarket accessories where a strong, removable threaded point is needed in wood, plastic, or composite substrates. For industrial applications, it is well-suited for building jigs and fixtures, assembling equipment, or performing maintenance on machinery and structures that require reliable, embedded threads.
