Design Philosophy
High-strength alloy steel cylinder head bolt (Grade 12.9, M10×73mm) designed to maintain continuous structural clamping force under extreme engine compression. Precisely rolled threads and black oxide coating ensure uniform axial tension, corrosion resistance, and reliable sealing for Isuzu commercial diesel engines.
How It Works
Threaded into the engine block through the cylinder head, this bolt clamps the head and gasket against the block. When tightened to specified torque and angle, it stretches elastically to generate clamping force that seals combustion pressure, coolant, and oil passages.
Problems It Solves
Fixes cylinder gasket blowouts, coolant leaks, and compression loss caused by stretched, corroded, or reused head bolts. New bolts restore proper clamping force and ensure reliable combustion sealing in 700P / NPR66 trucks.
