KZ InternationalENGINEERED CONSTRUCTION PRODUCTSA mechanical connection system for non-rotatable and non-movable reinforcing bars, providing a practical solution for challenging rebar splicing applications.


Verification of coupler performance through tensile failure testing.

Dimensional and torque verification using dedicated checking tools.


A clear sequence from tapping verification through final torque testing.
Tapping VerificationVerify the tapped connection before proceeding.
Measure NeckMeasure and record the neck dimension.
MBT SetupInstall rebar and bolt, then position the torque wrench.
Torque TestingTighten until the bolt breaks, then read the torque value.
