The lug nuts are M12 x 1.5 with a 60-degree conical seat, and you typically use a 19 mm socket to install or remove them.
In practice, the 2008 Honda Accord (eighth generation) uses five lug nuts per wheel on 12 mm studs. While this configuration is standard for stock wheels, aftermarket rims or spacers can require different nut sizes or seating shapes, so always verify with your vehicle’s manual or the wheel manufacturer before buying replacements.
Key specifications
These are the core measurements you need when sourcing replacements or inspecting your wheels.
- M12 x 1.5 thread size (12 mm diameter with a 1.5 mm pitch)
- 60-degree conical seat
- 19 mm lug nut hex size
- Five lug nuts per wheel
With these specs, stock nuts should fit standard wheels. If you have aftermarket wheels, verify seat type and diameter with the wheel manufacturer.
Additional notes for aftermarket wheels
When using aftermarket rims or spacers, lug nut specifications can differ. Always verify compatibility with the wheel manufacturer and consult the vehicle’s maintenance manual for the exact torque and seating requirements.
Seat and thread variations
Some aftermarket wheel setups may use different seat angles or pitches. Confirm the exact lug nut type before purchasing to avoid damaged wheels or unsafe installation.
