Bolts used for fastening engine cylinder heads

Bolts used for fastening engine cylinder heads, usually in a number of 2x no. cylinders. They must exert an axial load allowing a steady contact pressure to be maintained on the head gasket, such as to ensure that cylinders are perfectly sealed and therefore avoiding pressure losses in the combustion chamber and preventing any pressurized burned gases from leaking to coolant conduits.
At the same time, they must not apply excessive loads so as to prevent cylinders from being deformed with consequent malfunctioning of the engine. It follows that their mechanical strength must have a rather narrow tolerance range and their surface coatings must have well-defined and constant friction coefficients.
