Skirt Nut - Esco Equipment

Specifications

• Model Number: 40125
• Manufacturer: Esco Equipment ESCO
• Weight: 1.2 lbs
• Dimensions: 2 x 1.5 x 1.5 inches
• Thread Size: M22
• Hex Size: 33 mm

Key Features

• Integrated Skirt Design: A unique skirt extends 3/16 inch (5mm) into the stud hole, precisely filling the gap between the stud and the bolt. This design actively prevents wheel movement, known as "clocking," on hub-piloted wheels.
• Robust Strength: Engineered to withstand over 2,500 lbs of force, this skirt nut offers 50 times greater pull-off resistance than standard flange nuts.
• Corrosion Protection: A special graphite coating prevents the nut from rusting onto the hub, facilitating easier removal and prolonging hardware life.
• Enhanced Thread Engagement: Designed with nearly twice the number of threads compared to many conventional nuts, it ensures superior torque-holding ability and a more secure fit.
• Industry Compliance: This skirt nut meets and exceeds SAE J1965 standards for torque tension, ensuring reliable and consistent performance in heavy-duty applications.

Applications

• This Skirt Nut is specifically designed as a direct replacement for all M22 flange nuts on hub-piloted wheels.
• It is an essential component for securely fastening dual wheels on heavy-duty trucks, ensuring stability and safety.
• Ideal for vehicles where maintaining precise wheel alignment and actively preventing vibrations are critical for operational safety and efficiency.

Benefits

• Enhanced Safety: Eliminates wheel clocking and hub vibrations, significantly reducing the risk of loose wheels and potential "wheel-off" emergencies.
• Extended Tire Life: Prevents uneven tire wear, such as river wear and cupping, by ensuring true-running wheels and consistent clamping force. This also helps reduce tire rebalancing costs.
• Improved Fuel Efficiency: By eliminating wheel movement and reducing rolling resistance "drag," the skirt nut contributes to better vehicle fuel economy.
• Reduced Maintenance: The specialized graphite coating and robust construction ensure long-term durability and corrosion resistance, extending the service life of wheel hardware and simplifying maintenance procedures.
• Optimal Performance: Provides a secure and precise fit that maintains consistent torque, ensuring reliable operation even under the most demanding heavy-duty conditions.
