Locking / Shear Bolt Couplers are mechanical reinforcement couplers used to join steel rebars without the need for threading or welding. They are designed with locking or shear bolts that tighten onto the rebar to create a strong and secure connection, ensuring load transfer and structural continuity. These couplers are manufactured in various sizes to match different rebar diameters and are identified by their bar size compatibility and performance standards.
