This Muteki SR48 set delivers reliable wheel security with four open end locking lug nuts in black finish, designed for M12x1.25 threads and 60 degree conical seats. It fits popular Japanese vehicles including Honda Civic from 1988-2020, Acura models, and Nissan sports cars, providing theft deterrence without sacrificing strength. The 48mm shank length clears deep wheel designs while cold-forged chromoly steel resists stripping and wear during track or street use.
