About MBT Coupler - Mechanically bolted coupler

An MBT coupler is a threadless mechanical rebar splice that joins two TMT bars end to end using serrated saddles and bolts, with no bar-end threading and no bar rotation. Surya Engineering, a Mumbai-based manufacturer and supplier of rebar couplers, supplies MBT couplers to contractors and builders in Mumbai, Thane, Navi Mumbai and across Maharashtra.

What Is an MBT Coupler?

An MBT coupler joins reinforcing bars without lapping them. The bars sit inside the coupler body and are gripped by serrated saddles, tightened with bolts. Because no thread is cut on the bar, no threading machine is needed on site.

How Does an MBT Coupler Work?

1. Cut both bar ends square.
2. Slide the coupler over the bar ends.
3. Tighten the bolts in the sequence given by the manufacturer.
4. Inspect the joint as the project specification requires.

Benefits of MBT Couplers

• No threading machine needed: saves setup time and bar-end processing.
• No bar rotation: useful where bars are already fixed in place.
• Less congestion than lap splices: no overlap length, less steel, easier concrete placement.
• Fast installation with basic tools.
