Upset Parallel threaded coupler are suited to projects which required high volumes of couplers. They produce a full strength joint in the rebar connection. The ends of the bars to be joined are cut square and enlarged by cold forging to increase their core diameter and so ensure that the joint is stronger than the bar. The couplers are usually supplied attached to the reinforcing bars.

Step 1,Cutting: The end of the reinforcement bars is sawn square.

 

Step 2,Cold Forging: Use the upsetting Machine to enlarge the end of the reinforcing bar by cold forging, thus increasing its core diameter.

 

Step 3,Threading: Use the Threading Machine to cut the ISO standard metric thread.
