5450 Chrome Acorn Bulge Lug Nut – 1/2" Thread, 3/4" Hex, 1.38" Tall, 60° Degree

Part Number: 5450 

The 5450 chrome acorn bulge lug nut secures factory and aftermarket wheels that require a 1/2" right-hand thread and a 60° conical (tapered) seat. The bulge acorn shoulder spreads clamping force across a wider seating surface so the wheel sits centered and evenly torqued, while the polished chrome plating over durable steel resists rust and road grime. Available individually (1 PCS), by the box (50 PCS), or by the case (300 PCS) for tire shops, wheel installers, and DIY wheel swaps.

Important Fitment & Installation Information

Please confirm the 1/2" thread size, 3/4" hex, 60° conical seat, 1.38" overall height, and wheel mating surface before purchasing. An incorrect thread size or seat style may result in improper wheel installation.

Professional installation is recommended. Tighten lug nuts in a star (criss-cross) pattern to the vehicle manufacturer’s recommended torque specification, and re-torque after the first 50–100 miles of driving.
