KAMEARI L type reinforced head stud bolt

By using stud bolts, all the threads of the cylinder block can be used to the depths. As a result, the stress generated by tightening is dispersed throughout the thread, reducing cylinder bore deformation to approximately 1/2 and increasing accuracy.
Also, by using a large diameter washer, the ground contact area is increased and the tightening force is transmitted over a wide area.
