Bolted Rebar Coupler — Positional Splice
The only mechanical splice when rebar rotation is impossible. Split-shell halves clamp around both bar ends — no threading, no pressing, no bar movement required.
Six Reasons to Specify the Bolted Coupler
The bolted positional coupler solves the problem no other mechanical splice can — connecting bars already fixed in place that cannot be rotated or moved.
No Bar Rotation Needed
Split-shell halves clamp around both bar ends using high-strength bolts. Neither bar needs to move — the only mechanical coupler that works on bars already cast in concrete.
Retrofit & Repair
The only coupler type that connects rebar already embedded in concrete. Expose the bar end, fit the split halves around it, and torque the bolts — no demolition required.
Torque Wrench Only
No threading machine, no hydraulic press. A calibrated torque wrench is the only tool required on-site. Fast setup, minimal equipment transport, and simple site logistics.
Visual Verification
Correct bolt torque is immediately visually verifiable — inspectors can confirm correct installation at every connection before concrete placement. No specialist NDT required.
Full Tensile Capacity
When correctly torqued to specification, the bolted coupler develops the full tensile and compressive capacity of the connected reinforcing bars — both in tension and compression.

Is the Bolted Coupler Right for Your Project?
✅ Choose Bolted Coupler when:
- Existing bars are cast in or fixed — cannot be rotated
- Structural retrofit, extension, or repair work
- Bridge deck widening or abutment extension
- Building vertical extensions — connecting to existing columns
- Foundation underpinning and pile cap extension
- Site access prevents threading or pressing equipment deployment
⚠️ Consider Parallel Thread instead when:
- New construction — bars can be freely prepared and rotated
- ACI 318 Type 2 seismic compliance is specified
- Maximum tensile strength (≥125% Fy) is required
- Pre-assembly of sleeves before cage erection is planned
Retrofit, Extension & Repair — Worldwide
The bolted coupler is the structural engineer’s solution for any project where bars are already in position and cannot be moved.
Structural Extensions
Adding new floors or structural elements to existing reinforced concrete buildings. Bolted couplers connect new bars to exposed existing starter bars without any bar movement.
Bridge Widening
Deck widening and extension on existing bridge structures where bars are cast in position. No bar rotation needed — the split shells clamp around fixed bar ends.
Foundation Underpinning
Connecting new foundation elements to existing footings and pile caps. Exposed bar ends accept bolted couplers directly — no demolition or bar relocation required.
Seismic Strengthening
Adding confinement reinforcement and structural ties to existing columns and walls for seismic upgrade programmes — fixed bars connected using bolted positional couplers.
Industrial Upgrades
Extending or strengthening existing industrial floors, equipment foundations, and crane rails — where operational constraints prevent extensive demolition work.
Marine & Port Structures
Jetty extension, sea wall repair, and port berth widening projects where existing rebar is partially exposed and must be connected without movement or rotation.

Bolted Coupler — Common Questions
The bolted coupler is used specifically when the rebar is already fixed in position and cannot be rotated. This occurs on retrofit, extension, and repair projects where existing bars are cast into concrete. For new construction where bars can be freely prepared and rotated, parallel threading couplers are generally the preferred choice due to their ACI 318 Type 2 certification and higher tensile performance.
No threading or special end preparation is required. The bar end should be cleanly cut — standard bar ends exposed by demolition or cutting are suitable without further preparation. The split-shell halves clamp around the bar deformations using high-strength bolts torqued to specification.
Only a calibrated torque wrench is required at the point of connection. No threading machine, no hydraulic press, and no specialist equipment. This makes the bolted coupler ideal for sites with restricted access or limited plant logistics. BestNotch supplies torque specifications for every diameter.
BestNotch bolted couplers are available for bar diameters from 16mm to 40mm — the widest range of any coupler type in our range. This includes 16mm, 20mm, 25mm, 28mm, 32mm, 36mm, and 40mm. Contact us if your project requires a non-standard size.
Installation is visually verified by confirming correct bolt torque using the torque specification supplied with the order. A correctly torqued bolt is immediately obvious — a torque wrench that clicks at the specified value confirms installation. This visual verification method is faster than NDT and is accepted by structural engineers and inspectors worldwide.
