Leo Industries manufactures MBT rebar couplers engineered for fast, dependable reinforcement splicing without bar threading. MBT (Mechanical Bolted) couplers use shear-head bolts that clamp onto the rebar to create a high-strength mechanical connection, making them a practical choice for sites where threading machines are not available or where installation speed is critical. As MBT rebar coupler manufacturers, we focus on consistent machining, controlled bolt performance, and robust steel bodies that support reliable load transfer across the splice. Our solutions are widely used in infrastructure, commercial buildings, industrial foundations, retrofit works, and reinforcement corrections where downtime must be minimized.
Working Principle & Process Flow
An MBT coupler connects two rebar ends by mechanical gripping rather than threads. The bars are inserted into the coupler sleeve until they meet the internal stop. Shear-head bolts are then tightened using a standard impact wrench or torque tool. As tightening progresses, the bolts apply controlled clamping pressure that bites into the rebar surface and locks the bars in place. Once the correct torque is reached, each bolt head shears off at a predetermined point, providing a clear visual confirmation of proper installation. This process enables quick, repeatable splicing with reduced dependency on specialized on-site equipment.

Maintenance & Safety Tips
ChecklistLeoindustries
Pre-Installation
Clean the rebar surface near the splice to remove mud, scale, or loose rust
Confirm coupler size and bolt set match the bar diameter and splice requirement
Arrange a suitable impact wrench or torque tool with the correct sockets
Installation Practices
Insert both bars fully until they touch the internal stop for correct engagement length
Tighten shear bolts in a balanced sequence until bolt heads shear off completely
Inspect for uniform head shear and correct bar position to confirm completion
FAQs — MBT Rebar Couplers
Q1
What is an MBT rebar coupler?
An MBT rebar coupler is a mechanical bolted splice used to connect reinforcement bars without threading. It uses shear-head bolts that clamp onto the rebar and shear at a preset torque to confirm correct installation.
Q2
When should MBT couplers be preferred over threaded couplers?
MBT couplers are preferred when threading is difficult or slow, such as retrofit sites, tight work zones, urgent schedules, or locations where threading machines and trained operators are not readily available.
Q3
Do MBT couplers require special tools for installation?
No special threading tools are needed. Installation is typically done with a standard impact wrench or torque tool and suitable sockets to tighten the shear bolts.
Q4
How is installation quality verified on site?
Quality is verified by checking that bars are fully inserted and that all bolt heads have sheared off cleanly at the specified torque point, indicating the correct clamping load has been achieved.
Q5
Can MBT couplers connect different bar diameters?
Yes. Reducer couplers are used to connect two different bar sizes where required, helping maintain reinforcement continuity in transitions and correction works.
