Which best describes a mechanical connection which uses a seamless steel coupler and portable hydraulic press?

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

Answer: (A)

A seamless steel sleeve connected with a portable hydraulic press describes a cold forged steel sleeve. In this method, the bars are inserted into the smooth sleeve and the hydraulic tool applies pressure to forge the sleeve around the bars, producing a tight, high-strength mechanical bond without heating the metal. The term “cold” means no heat is used, distinguishing it from hot forging methods, and “seamless” indicates the sleeve is a single piece, which helps avoid weak points at joints. This approach is different from threaded couplings, which rely on screwed threads; end-bearing connections, which transfer load through bearing surfaces at the ends; and metal-filled sleeves, which use filler material rather than deformation to create the bond.
