 This kind of end upset foging parallel thread coupler can link steel bar Dia. from 12mm to 40mm.

The tensile strength of splicing can reach 1.1 times of the steel bar's. 100% reach bar break.

It widely used in key and big construction.

It meets Chinese standard JGJ107-2010,JG171-2005; American standard ACI318-2008 etc.
