Tomei Head Studs
Tomei

In order to secure the performance required of head gaskets, such as cooling, rigidity, and sealing, it is necessary to strengthen the combination of a cylinder head and a cylinder block. However, in combination with a common bolt and nut, bolting power concentrates on from third groove to the 1st groove of the screw, and the total bolting power cannot be increased beyond a certain value. Moreover, excessive stress is concentrated and may damage the bolt. Stud bolts, on the other hand, have been designed so that the bolting force is dispersed to all the screw threads and high bolting power is generated.
