Which best describes a mechanical connection consisting of a taper threaded sleeve that joins rebar with matching taper threads, preventing cross-treading during installation?

Which best describes a mechanical connection consisting of a taper threaded sleeve that joins rebar with matching taper threads, preventing cross-treading during installation?

• A. Threaded Steel Coupling
• B. Cold Forged Steel Sleeve
• C. End-Bearing Connection
• D. Hot Forged Steel Sleeve

Answer: (A)

A threaded steel coupling is the device described. It’s a mechanical splice that uses a sleeve with taper threads on the inside and matching taper threads on the rebar ends. As you tighten the connection, the taper guides the threads into proper engagement, preventing cross-threading and misalignment during installation. This allows two rebar pieces to be joined in a straight, continuous load path, transferring tension and shear through the threaded interface. Other sleeve options describe the manufacturing method or rely on bearing surfaces, which don’t capture the specific tapered-thread joining action described here.
