THREADED TUBE
INSERTS 
Whether you call these threaded tube inserts, weld bungs or threaded plugs, we have them. Ours are mild steel and are specially designed to fit our seamless DOM steel tubing.
They all have fine thread to accept heim joints, rod ends and strong fine threaded fasteners.
You can turn the shank down in the lathe to fit any tubing size. These can be welded using MIG, TIG or stick.
