• Anti-loosening function: Spring tension eliminates nut loosening caused by power line vibration or pole movement.

• Bolt compatibility: Fits 3/8"–3/4" bolts, matching common fastener sizes in power infrastructure.

• Corrosion resistance: Hot-dip galvanization protects against outdoor rust and corrosion for long service life.

• Bulk packaging: 1250–5000 pcs/carton reduces per-unit costs for large-scale utility projects.

• Easy installation: Slips onto bolts directly, requiring no specialized tools for assembly.

• Utility pole hardware: Securing nuts on crossarm/brace bolts to prevent vibration-induced loosening.

• Power transmission towers: Locking structural bolt nuts on steel tower components.

• Substation equipment: Stabilizing fasteners on transformers, switchgear, and busbar supports.

• Bolts/nuts (3/8"–3/4" diameter): For use with spring lock washers in power infrastructure fastening.

• Flat washers: Provide a smooth surface for the spring washer to exert tension.

• Anti-corrosion grease: Lubricates the washer to prevent rust and maintain spring tension.
