  • Features a 1/4-20 thread that is commonly used with correspondingly levelers and the external edges on these single point threaded inserts are designed to fit flush with the outside edge of the tube for a clean, finished look.
  • Steel threaded metal caster inserts are specifically designed to be inserted into Square tubular legs (not recommended for casters). As the insert is inserted into the tube, the star washer/clip flexes in the direction of entry, and its edges bite into the inside surface of the tubing, offering rigid support that prevents the clip from being removed. The deep setting ensures the insert stays securely in place.

  • Manufactured from heat-treated carbon steel with black oxide wings and a zinc-plated base, providing enhanced durability and strength when installed.
  • Perfect for commercial, industrial, and residential applications, these durable threaded inserts provide a strong, secure connection that won’t pull out, even with frequent movement or heavy use.
