Vehicle Fitment

• Universal fit - compatible with any vehicle using M12 x P1.25 thread pitch hub bolts (common on Nissan, Subaru, and other applications)

Fitment Notes

• Confirm your vehicle's exact thread size before ordering - a P1.5 pitch version (00B 738 1520B) is also available for applications that use that thread
• Nut may protrude past the wheel/fender on some vehicle and wheel combinations - check clearance before installing

Product Description

The Cusco 00B 738 12520B is a set of 20 M12 x P1.25 racing wheel nuts built from chrome-molybdenum steel (SCM435), chosen because its thermal expansion rate closely matches that of typical wheel studs - helping the nuts resist loosening even as temperatures climb during hard driving. The long, penetrating-type 48mm design is a deliberate balance between weight savings and the durability needed for repeated track or competition use.

Each nut uses a 17mm hex with a 60° taper seat for secure, centered wheel mounting, finished in black for a clean, understated look. Since this is a universal M12 x P1.25 fitment rather than a vehicle-specific part, it's important to verify your car's exact thread pitch and check wheel/fender clearance before ordering - Cusco also offers an M12 x P1.5 version for applications that use that thread instead.
