Description:

Made of high-strength rustproof steel and can withstand the high temperatures and high pressures generated during engine operation.. Secure the cylinder head: The cylinder head bolts lock the cylinder head to the cylinder block interface to securely fix the cylinder head to the block, forming an airtight seal and able to withstand high pressure.. Seal gases: The cylinder head bolts clamp the cylinder head tightly against the cylinder block. Together with the gasket or O-ring seals, they seal the interface between the intake manifold and cylinder block to prevent the escape of high-pressure gases.. Easy to service: The cylinder head bolts can be removed to allow access for routine servicing and major overhauls of the engine. This allows the mechanic to take off the cylinder head and access internal components such as valves and pistons..
