Product Description
The ring nut is a critical component for connecting mechanical equipment. Through its internal thread, it securely fastens with screws of matching specifications. These eye nuts are commonly used with external threaded columns for lifting various equipment including molds, chassis, and motors.
Surface Treatment Options
Standard ring screws typically have no surface treatment, but can be customized with galvanized passivation, chrome plating, or other finishes per GB5267-85 specifications. Post electrogalvanizing, material composition and mechanical properties are tested according to GB699 standards.
Quality Assurance
Thread inspection is performed using thread gauges and smooth limit gauges or universal gauges. The ring should be discarded if visible deformation occurs.
Lifting Safety Guidelines
When lifting with increased acceleration or impact, always select a load capacity lower than rated specifications. For 45° lifting angles, ensure bolt/nut supporting surfaces closely contact mating parts using washers to maintain ring alignment within 5° of plane deflection.
Material Considerations
Heat-treated special steel materials may exhibit reduced ductility, increasing risk of sudden failure before deformation occurs.
Surface Treatment Processes
Blackening Process
Blackening creates a protective oxide layer through chemical reactions, isolating metal from air to enhance corrosion resistance while improving aesthetic appearance and reducing workpiece deformation.
Galvanizing Process
Galvanizing applies a zinc coating for corrosion protection and aesthetic enhancement, available in silver-white, colored, or army green finishes after passivation.
