Dacromet grade 10.9 12-Point Gasket cylinder head bolt for engines

Cylinder-head bolts are the connecting elements between engine block, cylinder-head gasket, and cylinder head. The bolt tightening force is an important factor for the mutual sealing of combustion chamber, lubricant and coolant channels, and the ambient air. A task that must be performed perfectly with cold or extremely hot engines, at negative and high positive pressures.

When tightening (torquing) the cylinder-head bolts, the bolt force generates the so-called surface pressure, which is essential for achieving a perfect seal. Hereby, and in combination with the applied torquing method, the bolts have a strong effect on surface pressure quality.
