5455 Chrome Acorn Bulge Lug Nut – 12x1.5 Thread, 3/4" Hex, 1.38" Tall, 60° Degree
Part Number:5455
The 5455 12x1.50 chrome acorn bulge lug nut with a 3/4" hex, 1.38" overall height, and a 60° conical bulge seat. Manufactured from steel with a polished chrome-plated finish for secure, OE-style wheel mounting on factory and aftermarket wheels.
The bulge acorn seat provides a wider seating surface than a standard acorn lug nut, spreading clamping load across the wheel's seat for a more precise, vibration-resistant fit. Available individually, by the 50-piece box, or by the 300-piece case for shops and wholesale buyers.

Fitment: How to Confirm This Lug Nut Fits
Before ordering, confirm all five of the following against your vehicle and wheels:
- Thread size is 12x1.50 (not 12x1.25, 14x1.50, or 14x2.00)
- Seat type is 60° conical / tapered — not ball/radius or flat/mag seat
- Hex size of 3/4" clears your wheel's lug hole and center cap
- Overall height of 1.38" clears any cap or trim ring
- Wheel mating surface is compatible with a bulge acorn shank
An incorrect thread size or seat style can damage the wheel and lead to improper installation.
Installation & Torque
Install by hand first to avoid cross-threading, then tighten in a star pattern to the vehicle manufacturer's recommended torque specification using a calibrated torque wrench. Re-torque after the first 50–100 miles of driving. Professional installation is strongly recommended.
