The wheel stud thread size on a 2006 Honda Civic is M12 x 1.5, with a 5x114.3 mm bolt pattern.
Along with the thread size, the lug nut seating and torque are important for safe wheel installation. Factory lug nuts typically use a 60-degree conical seat and require a 19 mm wrench; the suggested torque is about 80 ft-lbs (108 Nm). However, some trims or aftermarket wheels may use different specs, so always confirm using the owner's manual or wheel specification sheet for your exact vehicle configuration.
