In most stock Acura Integra models, the lug nuts are M12x1.5 with a 60-degree conical seat, and they use a 4x100 bolt pattern. The typical wrench size is 19mm.
The Integra line spans multiple generations (DA, DC1, and DC2) from 1990 through 2001. Across these stock configurations, the standard lug nut specifications are shared, though always verify your exact year and wheel type when replacing nuts or wheels. If you are dealing with aftermarket wheels or a later model variant such as the RSX, the specs can differ, so always confirm with the wheel manufacturer or a service manual.

What to check if you have aftermarket wheels or a different generation
When upgrading or changing wheels, verify each component to ensure compatibility and safety.
- Bolt pattern: Most Integras use 4x100, but some aftermarket wheels may require exact matching. Confirm with the wheel manufacturer or a shop.
- Thread pitch: While M12x1.5 is common, some aftermarket setups use different pitches. Measure or consult documentation before purchasing lug nuts.
- Seat type: Conical seats are common on Hondas/Acuras, but some wheels use ball or flat seats. Choose lug nuts that match the wheel seat type.
Always torque lug nuts to the manufacturer’s specification and reinstall in a star pattern to ensure even seating. If in doubt, seek professional assistance or consult the owner's manual for your exact model year.
