American Forge & Foundry 175 Ft-lb Yellow Torq Limit. Extens. (40306)
The American Forge & Foundry 175 Ft-lb Yellow Torq Limit. Extens. (40306) is an essential tool designed to ensure accurate and consistent torque application when working on vehicle wheels. Specifically engineered to prevent the common problem of overtightening lug nuts, this professional-grade torque stick helps protect critical vehicle components from damage. Its unique design ensures that the socket stops turning once the specified torque of 175 ft-lbs is achieved, eliminating the guesswork often associated with impact wrench use. Crafted from professional-grade chrome molybdenum spring steel, this extension is built for reliability and long-term performance in demanding workshop environments. The bright yellow powder-coat finish not only provides superior scratch and corrosion resistance but also allows for quick identification among other tools. Ideal for use with 3/4" air impact tools, the AFF 40306 offers a straightforward solution for proper wheel installation, enhancing both safety and component longevity.
KEY FEATURES AND BENEFITS:
Prevents Overtightening: Reduces the risk of overtightening wheel lug nuts, which can lead to damaged studs, rotors, or wheels.
Component Protection: Helps prevent costly damage to wheels, wheel studs, and brake rotors that can result from inaccurate or excessive torque.
Consistent Torque Application: Ensures the socket stops turning once the specified torque of 175 ft-lbs is achieved, providing reliable and consistent fastening.
Professional Grade Construction: Made with chrome molybdenum spring steel for strength and resilience, designed to withstand the demands of regular use in professional settings.
Corrosion and Scratch Resistance: Features a powder coat paint finish that offers superior protection against scratches and corrosion, extending the tool's lifespan and maintaining its appearance.
Secure Socket Connection: Equipped with a ball detent that securely holds sockets in place, preventing accidental disengagement during operation.
Clear Identification: Size and torque rating are permanently roll-stamped on the extension for quick and easy identification, ensuring you select the correct tool for the job.
Enhanced Clearance: Its long pattern design provides additional clearance from the tire, making it easier to access lug nuts, especially on vehicles with deep-set wheels.
Air Impact Tool Compatibility: Specifically designed for use with 3/4" size air impact tools, making it a perfect complement to your existing pneumatic equipment.
Drive Size: 3/4"
Torque Rating: 175 ft-lbs
Color: Yellow (F)
Material: Chrome Molybdenum Spring Steel
Included: One (1) American Forge & Foundry 175 Ft-lb Yellow Torque Limiting Extension (40306)
Select the Correct Socket: Choose the appropriate wheel socket that fits your vehicle's lug nuts.
Attach Socket to Torque Stick: Firmly attach your selected socket to the 3/4" drive end of the American Forge & Foundry 40306 Yellow Torque Limiting Extension. Ensure the ball detent clicks into place for a secure fit.
Attach to Impact Wrench: Connect the 3/4" drive end of the torque limiting extension to your 3/4" air impact wrench.
Position on Lug Nut: Place the socket firmly onto the lug nut you intend to tighten.
Apply Torque: Activate your air impact wrench. The torque stick will allow the lug nut to be tightened until it reaches 175 ft-lbs. Once this torque is achieved, the extension will flex and absorb the impact, preventing further tightening of the lug nut, even if the impact wrench continues to operate briefly.
Verify (Optional but Recommended): For critical applications, you may choose to verify the final torque with a calibrated torque wrench after using the torque stick.
