Designed for KYO-EI M12 MONOLITH Wheel Nuts
The CMF1K cap is designed to fit inside the internal opening of KYO-EI's M12 MONOLITH wheel nuts. Once installed, the cap helps hide the exposed end of the wheel stud and gives the wheel nut installation a cleaner and more complete appearance.
Black Finish
The Black CMF1K cap is the perfect choice for customers wanting a subtle, factory-style finish inside their MONOLITH wheel nuts.
When combined with Glorious Black MONOLITH nuts, the black inner cap creates a discreet and uniform appearance while helping conceal the exposed end of the wheel stud.
Helps Protect the Hub Bolt
KYO-EI recommends the MONOLITH Inner Cap for users concerned about corrosion of the vehicle's exposed hub bolts.
By fitting inside the MONOLITH nut, the resin cap helps shield the exposed end of the stud while also improving the finished appearance of the wheel installation.

Compatible MONOLITH Nuts
CMF1K is the M12 Black version of the MONOLITH Inner Cap and is designed specifically for KYO-EI M12 MONOLITH wheel nuts.
Compatible with both M12 thread-pitch versions of the MONOLITH T1/06, including:
- MN01GK – M12 × P1.5 – Glorious Black
- MN03GK – M12 × P1.25 – Glorious Black
Installation
The cap is secured by inserting its retaining tabs into the internal thread grooves of the MONOLITH wheel nut.
Make sure each cap is inserted fully and squarely into the wheel nut. KYO-EI recommends using the dedicated MONOLITH adapter to ensure the cap is properly seated.
The CMF1K is manufactured from resin and has a maximum heat resistance of approximately 100°C. KYO-EI advises removing the caps before racing or other severe high-temperature use.
When the M12 inner cap is installed, the effective thread length of the MONOLITH nut becomes 25mm. Extra care is therefore required on vehicles fitted with long wheel studs.
Do not use an impact wrench with the caps installed, as vibration may cause the caps to loosen or detach.
