Information - Head Bolts & Cylinder Head Bolt Kit

The performance accuracy of all elements of the engine is very important and this became an axiom. And the tightening of the cylinder head bolts is not an exception. And the reason is simple. Imagine the load experienced by all elements of the mount: strong temperature fluctuations, and constant vibration. As a result of numerous studies inquired by professionals, the weight consists of 5000 kg or more. Imagine what kind of pressure undergoes every engine bolt while accelerating. To ensure the connection between the block and the cylinder head, you have to make sure that the bolts are stable long enough.

In most cases, the bolt is oblongated. Screwing this item in a block that has been affected by corrosion, torque is increased by several tens of units before the parts were linked up. If you have already tightened the bolt, you must know that the tension increasing is gradual and the material will initially take it`s elastic state, until, finally, will become ductile.

Later a further tension will lead to irreversible deformation of the material. In this state, the torque does not increase with any further tension. In practice, this condition is almost impossible to observe, if only the bolts are not lubricated with grease or oil in order to reduce the frictions to zero. Do not forget that the surface of the block and cylinder heads must be very well processed, they should not be wavy.

Particularly important are the transitions from one item to another. Remember that all replacement parts must be certified, like those offered in our online store. And apart from cylinder head bolts, you can also purchase expansion flanks, valve injectors and other parts and components.
