To ensure optimal performance of head gaskets, including efficient cooling, enhanced rigidity, and effective sealing, it is imperative to reinforce the combination of a cylinder head and a cylinder block. Traditional methods involving common bolts and nuts face limitations, as the bolting power tends to concentrate primarily from the third to the first mountain of the screw, reaching a plateau in total bolting power. This issue persists even when utilizing stronger bolts, potentially leading to concentrated stress and bolt damage. In contrast, the implementation of stud bolts incorporates dynamic design principles in their threading. This design disperses the bolting force across all screw threads, generating robust and evenly distributed bolting power. Notably, this innovative solution is tailored to complement Toyota 4AG engines, ensuring optimal performance without compromising durability.
