| Customization |
- Special Materials (Inconel, Titanium for Aerospace)
- Anti-Static Coatings (For Explosive Environments)
- Laser Etched Part Numbers for Inventory Control |
- Vibration Resistance: Helical design absorbs shocks and prevents loosening in high-vibration environments (e.g., transportation, industrial machinery), reducing maintenance costs.
- Temperature Versatility: Stainless steel and spring steel variants handle extreme temperatures (-196°C to +600°C), making them suitable for aerospace, automotive, and energy sectors.
- Global Industry Compliance: Meets ISO, ASME, DIN, and automotive standards (e.g., IATF 16949), ensuring approval for OEM and aftermarket applications worldwide.
- Corrosion Protection: Dacromet/Geomet coatings offer superior salt spray resistance (1000+ hours), ideal for offshore, marine, and outdoor infrastructure projects.
- Cost-Effective Engineering: Prevents bolt loosening without additional locknuts, simplifying assembly and reducing component costs in large-scale projects.
