Precision Tapered Thread
Self-locking tapered thread profile ensures tight engagement and high load transfer efficiency.
Konnexa Tapered NEX Coupler Series
The Konnexa TaperedNEX Series is a high-efficiency mechanical splicing system engineered for rapid deployment and robust structural alignment in reinforced concrete construction. Utilizing an advanced tapered-thread profile, the system provides a self-aligning, torque-tightened mechanical connection that ensures high-integrity load transfer under both tension and compression.
The Konnexa advantage - Switching from traditional lapping to the Konnexa Series typically delivers a 15-20% reduction in total steel consumption while significantly shortening structural installation timelines.

Installation Sequence
Three Steps to a Full-Strength Splice
A precise bar preparation process and controlled torque engagement bring the tapered connection together quickly and consistently.
Prepare the bar
Cut and prepare reinforcement bar ends to produce clean, accurate tapered threads ready for engagement.
Tighten to torque
Use a calibrated torque wrench to complete the connection and verify a secure mechanical splice.
Align and engage
Guide the coupler onto the first threaded bar, then bring the second bar into the self-aligning taper profile.
The TaperedNEX™ Solution
The progressive taper creates tight thread contact along the splice interface. The result is a compact, full-strength mechanical connection that supports fast reinforcement assembly without lap-splice congestion.
Applications
From skylines to seabeds, TaperedNEX™ holds it together.
Designed for demanding projects where the mechanical splice must perform as reliably as the parent bar itself.
