Round Double Star Metal Inserts

Outwater Industries offers a wide variety of threaded inserts, including our square double star metal inserts. The double star insert offers a deeper setting that will not pull out with any jerky movement or rolling and was designed to easily fit easily into a variety of steel tubing and legs. Threaded square tube inserts are ideal for use with casters but can also be used with steel tables, displays and other applications.
These double star inserts offer a flush fitting for a clean, sleek appearance and are suitable for industrial, commercial and residential environments. Our threaded square tubing inserts are manufactured from a durable steel that provides long-lasting quality in any application. They can be used with 16 to 18 gauge tubing and are available with either a 5/16-18 or 3/8-16 thread. We offer the threaded square tube inserts in four popular sizes:

  • 3/4"
