High-quality mechanical coupler for building parallel thread low carbon steel bar coupler

• Made of high-grade low carbon steel (e.g., Q235 or 45# steel, compliant with building material standards) with excellent tensile, yield, and impact resistance.

• The mechanical properties of the coupler match or exceed those of the connected low carbon steel bars, ensuring the overall load-bearing capacity of the reinforced concrete structure is not compromised—even under dynamic or heavy loads (e.g., seismic forces, structural dead weight).

• Features precision-machined parallel threads (thread pitch, diameter, and tooth profile strictly adhere to industry standards like GB/T 1499.3 or ASTM A615). The thread fit is tight and uniform, eliminating gaps that could cause connection looseness.

• Enables "full-thread engagement" between the coupler and steel bars: when installed correctly, the bar threads fully penetrate the coupler, distributing stress evenly across the connection and avoiding localized stress concentration (a common cause of connection failure).

• No need for on-site welding or grouting—only requires matching pre-threaded steel bars to be screwed into the coupler (can be operated with standard hand tools or electric wrenches).

• The parallel thread structure allows for quick alignment of steel bars, reducing installation time by 30%–50% compared to traditional welding methods. It also minimizes skill requirements for operators, ensuring consistent installation quality across projects.

• Effectively resists corrosion from moisture, concrete alkaline substances, or outdoor environmental factors (e.g., rain, humidity), preventing rust-induced degradation of the connection over long-term use and extending the service life of the reinforced structure.

• All components (coupler body, internal threads, and auxiliary parts) undergo strict dimensional inspection (via precision measuring tools like thread gauges or calipers) to ensure uniform specifications.
