QSC 3/4-16 RH Threaded Weld In Bung Steel Adapter

The QSC 3/4-16 RH Threaded Weld In Bung is a steel tube adapter designed to provide a permanent, precisely threaded connection point inside 1-1/2 inch OD tubing with 1.000 inch ID and 0.250 inch wall thickness. Manufactured from 1045 mild steel, it offers a balance of weldability and mechanical strength that makes it suitable for fabrication work on suspension linkages, roll cages, steering assemblies, and other structural applications where a threaded joint is needed inside a tube.

The right-hand 3/4-16 thread is machined prior to shipping, so once the bung is welded into place, it is ready to accept a matching rod end, bolt, or other threaded hardware without any additional tapping or machining. The precise tube sizing ensures the bung sits flush inside the specified tubing dimensions for a clean, strong weld. Because the material is mild steel rather than stainless or alloy, the bung should be protected with paint or coating if it will be exposed to moisture or corrosive environments.
