Engineering details

Small details. A critical job.

Head studs help hold the cylinder head and gasket against the block. The hardware, surface preparation, lubrication, and tightening procedure all contribute to the finished assembly.

A secure starting point.

Head studs help secure the cylinder head and gasket to the engine block. Follow the installation diagram for your application when positioning the studs.

Designed to be worked with.

Broached ends provide an Allen-key interface for fitting and removing the studs. Use the tool size specified in your kit’s installation instructions.

Built through a defined process.

XOTIC 7200 alloy studs feature threads rolled after heat treatment. Follow your kit’s instructions for lubrication, tightening sequence, and torque requirements.

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
