100mm Nickel Cylinder Gasket Head Stud Bolt Kit Grade 12.9

Black color grade 12.9 Cylinder Gasket Head Stud Bolt Kit​

Bolts that are tightened beyond their elastic limit (yield point) into the plastic region ensure high and uniform bolt clamping forces. An important prerequisite for reliable sealed joints without retorquing. In this respect, stretch bolts offer decisive advantages over rolled shank bolts. By reducing its shaft diameter, the bolt is able to respond elastically to dynamic sealing gap movements, i.e. adaptation is greatly improved.

Torque-angle Method
In the first step, the bolt is snugged down to the cylinder head by means of a pretorque. With the second step, the so-called torque or tightening angle, the bolt is tightened into the plasticregion, i.e. beyond its elastic range.
