Clip Nut Inner Wheel Nut M22 × 1.5 Thread High-Quality Carbon Structural Steel with Anti-Rust Treatment for ISUZU NPR NKR NQR

The Clip Nut (Inner Wheel Nut) with OEM numbers 9091105220 / 9-09110522-0 (cross-reference 0911105220 / 0-91110522-0) is a verified direct-fit replacement for ISUZU NPR / NKR / NQR / NMR85 series trucks. This nut is a front/rear hub inner nut, responsible for securely fastening the wheel assembly to the hub and is a critical component for vehicle driving safety.

The clip nut (inner nut) is installed on the wheel stud (double-ended stud) and works with the stud to generate clamping force, firmly pressing the wheel assembly against the hub mounting surface. As an inner nut, it works in conjunction with the outer nut to form a double-nut locking structure, preventing the wheel from loosening or detaching while driving. This product features an M22 right-hand thread and a hex head design for easy installation and removal using standard socket wrenches.

Replace immediately if any occur:

• Loose/Wobbly Wheel — Wheel vibration or steering wheel shaking while driving (insufficient clamping force due to loose nuts)
• Damaged Threads — Nut rotation feels rough, sticking, or stripped during installation (worn or deformed threads)
• Severe Corrosion — Heavy rust on nut surface; worn hex head edges (compromising tool engagement and torque application)
• Broken Wheel Stud — Fatigue fracture of stud caused by prolonged loose nut operation (serious safety hazard)
• Uneven Tire Wear — Irregular tire wear patterns (poor wheel alignment due to improper fastening)
