The lug nuts on a Honda S2000 use a standard M12 x 1.5 thread with a 60-degree conical seat, and you’ll typically need a 19 mm socket. This sizing applies to both AP1 (1999–2003) and AP2 (2004–2009) models. This article breaks down the exact specs and practical notes for replacement or upgrade.
Core specifications you should know
These are the essential measurements to verify when servicing S2000 wheels or buying replacements:
- Thread size: M12 x 1.5 (metric, 1.5 mm thread pitch)
- Seat type: 60-degree conical (tapered) seat
- Socket size: 19 mm (across-flat hex for OEM lug nuts)
While many Honda/Acura vehicles use the same basic lug-nut standard, always verify that the replacement nuts match both the seat angle and thread pitch of your wheels. Using the wrong seat or thread can damage the wheel, studs, or lug nuts.
Additional notes for replacement and upgrades
If you're considering aftermarket wheels or upgrading to locking nuts, keep these considerations in mind:
- Ensure the lug nuts' seat matches your wheel (60-degree conical seats are common for OEM Honda wheels).
- Use lug nuts with the same thread specification (M12 x 1.5) and appropriate wheel compatibility.
- Use the correct lug-nut type and torque specification as recommended by Honda for the S2000 or your wheel manufacturer.
- Some wheels may require locking lug nuts or a different nut length; in those cases, consult the wheel maker or a trusted tire shop.
Approaching replacement with the proper spec helps prevent stud damage and ensures the wheels stay secure on the road.
Summary
In brief, Honda S2000 lug nuts use M12 x 1.5 threads with a 60-degree conical seat and a 19 mm socket size. This applies to both AP1 and AP2 models. When replacing, match the seat type and thread pitch to your wheels, follow the manufacturer’s torque specifications, and consider any wheel-specific requirements such as locking nuts if applicable.
