05 / Understand the connection

How a head stud works.

The stud stays in tension. The head and gasket stay clamped. See how the parts work together.

Inside the connection
A head stud in cross-section A blue stud threads into the engine block and passes through a clearance hole in the cylinder head. A nut and washer sit above the head. Tightening the nut stretches the stud slightly and compresses the head and gasket against the block. White arrows show tension in the stud; blue arrows show the clamping forces on the joint. 3 4 2 1 5 6
