Wheel Mate Muteki SR48 Open End Locking Lug Nut Set of 4 - Black 12x1.25 48mm for Honda Civic 1988-2020, Acura Integra RSX, Nissan 350Z
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.
Key Features
- Cold-Forged Chromoly Steel: SCM440 alloy forging creates dense structure for high tensile strength over 150,000 PSI, handling extreme torque and impacts.
- 48mm Extended Shank: Tall profile fits low-offset and concave wheels, preventing bottoming out on hubs common in performance setups.
- Open End Design: Allows standard 19mm socket access on both ends for fast installs, no special tools needed beyond included key.
- Black Oxide Finish: Resists rust and chips, blends with black wheels for clean OEM-plus appearance that lasts through washes and weather.
- Precision Threads: Rolled M12x1.25 threads ensure smooth engagement and consistent torque retention up to 100 ft-lbs.
