Technical Details and Specifications

The Mahle GS33573 cylinder head bolt set features a triple square fastener head style, allowing for precise torque application with compatible tools. Made from high-quality steel, these bolts provide the strength necessary to withstand engine operating conditions. The torque to yield (TTY) design means the bolts stretch slightly during installation to maintain optimal clamping force, reducing the risk of loosening over time. Washers are included with the bolts—4 with small washers and 2 with large washers—to ensure even load distribution and proper sealing of the cylinder head assembly. This set meets OEM standards, making it suitable for professional engine rebuilds or repairs.
