Usually characterized by a rather large ( >10) slenderness or length to diameter ratio, they must however have very contained rectilinearity values. Typical 10.9 and 12.9 strength ratings, more and more so they are designed with custom strength ratings, even with very narrow Rm ranges.
They work in the plastic range and are usually tightened based on torque + rotation. Depending on the architecture of the engine and its dimensions, they may have different head shapes and in some cases require a washer. In most cases they are phosphated and oiled.
