FAQ of Shell Type Lock Bolt Kit:

The shell type lock bolt is divided into a forged shell made of aluminum alloy 7075- T6 material and SCM440 high strength forging screw. When installing the shell bolt, the shell is screwed down, the bolt is installed first, and the bolt is installed with a socket of 17 mm. The torsion is as follows:
Since the BONOSS extended bolts have the same or higher level and performance than the factory bolts, which can withstand greater tightening torques. However, we recommend using the torque recommended by the original car for locking due to the different wheels and different original lug thread.

In general, the tightening torque is as follows:
M12x1.25: 113NM(83.3Ft-tb)
M12x1.5: 113NM(83.3Ft-tb)
M14x1.25: 140NM(103.5Ft-tb)
M14x1.5: 140NM(103.5Ft-tb)

An impact wrench is not recommended, an incorrect torque wrench may destroy the wheel bolts and wheels.
Once the installation screw is complete, just screw the shell by hand. The installation of the shell part needs attention. The shell part is mainly used for aesthetic purposes, which does not bear the role of fixing the wheel. And it also is thin and basically unstressed during use, so it is not suitable for excessive force during installation. We recommend A torque of 5-15NM.
In a box of Shell Type Lock Bolt Kit, we give away 4 anti-theft bolts, if you need to replace them, we recommend one for each hub, and there is a special sleeve for installing anti-theft bolts in the kit. Please pay attention to the use them.

Can the shell of BONOSS shell bolts be replaced?

The shells of the BONOSS shell type bolts can be replaced to use, but which cannot be used with other brands of shells because of BONOSS unique structure.

Will the shell of the BONOSS shell bolt fade?

The shell of the BONOSS shell-type bolts used the “Hard Anodized Coloring” project, which is bright in color and very artistic. There maybe happen darkening and fading after a long time due to various factors such as environmental impact and corrosion of alkaline substances. Do believe that BONOSS will use more updated technologies to protect the color and extend the beautiful color time.
