“Compression bolt” for exclusive use of through nut (long type) is a product in which a steel ball and a spring are built in an aluminum bolt, and it is a product to be attached to the excess screw part of the through nut that was actually attached (see the figure below). You can create an appearance that looks like you are wearing a super long hub bolt !!
Moreover, the tension of the spring improves the loosening prevention effect of the attached nut.



Patent registration No. 6638005

* This product “compression bolt” is exclusively for through nuts (long type).
* Be sure to install the nut with the nut attached to the vehicle (retrofitting).
● For installation, use the included 6HEX, L-type wrench.
* The maximum tightening torque of this product “compression bolt” is 4N ・ m (0.4kgf ・ m) .
If more torque is applied, the tip of the bolt may be damaged and the elasticity of the spring may be lost.
* The nut screwing allowance “above figure” varies depending on the amount of hub bolt protrusion of each car manufacturer’s model.
It also changes when spacers are installed or long hub bolts are used.
When installing, check the total length of the nut and the screwing allowance, and calculate the amount of protrusion of the “comp bolt”.
* This product “compression bolt” requires an extra screw length of “8 mm or more” “above figure”.
* Never use the product if it protrudes from the vehicle fender after installation.
* This product has a washer effect due to the elasticity of the coil spring, but it cannot completely prevent the screws from loosening.
Regular retightening of the wheel nut body and this product is required.
* To remove the wheel, first remove the “comp bolt” and then the nut.
