Core features of Hexagon Slotted and Castle Nut
- Slotted design: Cooperates with cotter pins (inserted through slots and bolt holes) for permanent anti-loosening, suitable for high-vibration environments
- Hexagonal body: Compatible with standard wrenches, easy torque application and assembly
- High strength: Matches high-grade bolts, resistant to tensile/shear forces in heavy-load scenarios
- Reusable: Cotter pin can be replaced for repeated disassembly/assembly without damaging the nut
- Wide application: Ideal for machinery, automotive, agricultural equipment, and critical fastenings requiring fail-safe anti-loosening
