The eye nut is a critical component for connecting mechanical equipment. Through its internal thread, it securely connects with screws of matching specifications. These ring nuts are commonly used with external threaded columns for lifting various equipment including molds, chassis, and motors.

Standard ring screws typically have no surface treatment, but can be customized with galvanization passivation, chrome plating, or other surface treatments as required, in accordance with GB5267-85 specifications.

After electrogalvanizing, material composition and mechanical properties are tested according to GB699 standards. Routine inspections include thread verification using thread gauges and smooth limit gauges or universal gauges.

For 45° lifting applications:

• Implement measures like sinking holes to ensure the bolt/nut supporting surface maintains close contact with mating parts
• Use appropriate washers to align both rings in the same plane
• Maintain deflection within 5° from the plane containing the axis

Warning: Special steel materials with heat treatment for enhanced mechanical properties may exhibit reduced ductility, increasing risk of sudden failure before overload deformation occurs.

Carbon steel offers exceptional performance characteristics:

• High Strength: Withstands significant external forces and pressures for construction, automotive, and aerospace applications
• Superior Wear Resistance: Ideal for tools, machine parts, and industrial equipment
• Excellent Formability: Easily processed through cold working, hot working, and forging
• Cost Effective: Competitive pricing for large-scale industrial use

Proper maintenance preserves stainless steel's corrosion resistance and appearance:

Methods:

• Use specialized stainless steel cleaners (avoid acidic/abrasive products)
• Rinse with clean water (avoid hot water)
• Dry thoroughly with clean cloths
• Avoid hard abrasives that could scratch surfaces
• Perform quarterly comprehensive maintenance

Maintenance Process:

1. Gather appropriate cleaning tools and materials
2. Remove surface dust with dry cloth
3. Apply cleaner evenly and wipe thoroughly
4. Rinse completely to remove residue
5. Dry completely and inspect results
