Phoenix USA 1-1/16" Hex w/ 5/8" ID Lug Nut (39946)
KEY FEATURES AND BENEFITS:
Precise Fit for Alcoa Wheels: Specifically designed with a 5/8" inside diameter and thread pitch (5/8" x 1.5) to match the studs on Alcoa aluminum wheels, ensuring a secure and accurate fit.
Two-Piece Flange Design: Features an integrated flange and separate washer, which helps to distribute clamping pressure uniformly, reducing the risk of wheel damage and ensuring a tight, lasting connection.
Optimal Hex Size: The 1-1/16" hexagonal head allows for easy and effective tightening and loosening using standard lug wrenches or sockets.
Compatibility with Hub Covers: Engineered to work seamlessly with Phoenix USA's hub cover systems, allowing for both secure wheel mounting and the ability to install decorative or protective hub covers.
Durable Construction: Likely manufactured from high-quality steel to withstand the stresses of wheel mounting and the rigors of road use, offering long-lasting reliability. Some variations may include stainless steel components for enhanced corrosion resistance.
Part Number: 39946
Hex Size: 1-1/16"
Inside Diameter (ID): 5/8"
Thread Pitch: 5/8" x 1.5
Type: 2-Piece Flange Lug Nut (with integrated washer)
Material: Primarily steel (potential for stainless steel covers or components in some variations)
Intended Use: Alcoa aluminum wheels, potentially compatible with specific 17.5" trailer wheels (e.g., 661401)
Ensure Proper Wheel Alignment: Position the Alcoa aluminum wheel correctly onto the wheel studs.
Hand-Tighten the Lug Nut: Place the Phoenix USA 39946 lug nut over a wheel stud and hand-tighten it clockwise until it is snug against the wheel. Repeat this for all lug nuts on the wheel.
Use a Torque Wrench: Consult your vehicle or wheel manufacturer's specifications for the correct torque value. Using a torque wrench with a 1-1/16" socket, tighten each lug nut in a star pattern (opposite nuts tightened sequentially) to the specified torque. This ensures even pressure distribution.
Re-Torque After Initial Use: After driving a short distance (typically 50-100 miles), it is recommended to re-check and re-torque the lug nuts to ensure they have not loosened.
Inspect Regularly: Periodically inspect your lug nuts for any signs of damage, corrosion, or loosening. Replace any damaged or worn lug nuts immediately.
