12-point bolt for MAK 16M453AK

The 8924272 12-point bolt serves as a critical fastening component within the MAK 16M453AK engine assembly. The 12-point head design allows for increased contact area with the installation tool, which supports precise torque application during the assembly of internal engine components. This fastener is engineered to maintain structural integrity under the operational loads and thermal conditions typical of large-scale diesel engines used in marine propulsion and power generation applications.

This component is compatible with the MAK 16M453AK engine model. The bolt features a nominal diameter of 11/16 inches, a thread pitch of 11 threads per inch, and a total length of 6.90 inches. It is manufactured to meet the specific dimensional requirements for this engine series, ensuring proper fitment and clamping force for the intended assembly points.

In heavy machinery and large diesel engines, bolts of this configuration are used to secure major structural elements, such as connecting rods, main bearing caps, or cylinder heads. These fasteners are designed to withstand the dynamic forces generated during engine operation, providing the necessary tension to keep mating surfaces securely joined throughout the service life of the engine.
