Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N177-501 is a galvanized hook and eye turnbuckle rated for demanding marine, industrial, and construction environments where corrosion resistance and load-bearing strength are critical. The body features hex heads for fast, tool-assisted adjustment without specialized tooling. End fittings are heat treated for added tensile strength. The safe working load (SWL) is 1,040 pounds, making this turnbuckle a reliable choice for tensioning applications that require a verifiable load rating and corrosion protection in harsh or outdoor conditions.

This turnbuckle is sized at 0.5 inches x 6 inches and is well suited for rigging, bracing, tensioning cables or rods, and structural tie-back applications in marine, construction, and general industrial settings. It meets Federal Specification FF-T-791B, Type 1, Form 1, Class 6, confirming compliance with established government standards for turnbuckle performance and dimensional requirements. This listing includes a package quantity of 10 units, sold in bulk format.

Compatibility

Designed for use in marine, industrial, and construction applications where maximum corrosion protection and tensioning strength are required. Suitable for cable, rod, and structural tensioning assemblies that call for a hook-and-eye configuration in the 0.5-inch body size class.

Installation Notes

Turnbuckles of this type are typically installed by riggers, construction tradespeople, or marine service professionals. Before installation, ensure all mating hardware hooks, eyes, cables, or rods is rated equal to or greater than the 1,040-pound SWL of this fitting. Do not exceed the rated safe working load. Inspect threads and body for damage before tensioning, and use a locking device or seizing wire where vibration or dynamic loading may cause the body to back off over time.
