L9 Collar Lock nuts Cad. Yellow & Wax (usa) (Inch)
USA‑made L9 Collar Locknuts with Cadmium Yellow & Wax finish deliver extreme strength, controlled torque behavior, and secure locking performance for demanding structural and mechanical applications. Manufactured from premium alloy steel and heat‑treated to meet Grade L9 performance standards, these locknuts provide the highest level of tensile and proof‑load capability available in a hex‑style locking nut.
The collar locknut design incorporates an extended bearing surface that improves thread engagement, enhances joint stability, and resists loosening under vibration and heavy load. The Cadmium Yellow plating with Wax lubricant offers exceptional corrosion protection, reduced friction during assembly, and consistent torque‑tension characteristics — making these nuts ideal for critical, safety‑sensitive installations.
These fasteners are engineered for environments where failure is not an option.
