Bolt, Cylinder Head
The FP Diesel 23530768 head bolt is engineered to restore factory-strength cylinder head retention on Detroit Diesel Series 50/60 platforms. Head bolts can stretch or lose torque through heat cycles, leading to gasket failure and compression leaks. This direct-fit replacement matches OEM dimensions and tensile strength, using a Grade 10.9 hex-head design for consistent torque hold. Ideal for rebuilds and head service, it helps keep your diesel sealed, stable, and dependable.

Specifications
FP Diesel part 23530768 is an OEM-style cylinder head bolt used on Detroit Diesel four-cycle engines where precise clamping is critical. Catalogs identify it as a Series 50/60 head bolt with M16 x 2.0 threads and a 175 mm length, produced to a Grade 10.9 strength rating. Proper head bolt preload prevents head lift, coolant/oil crossover, and combustion leakage that can damage the head gasket and block. Manufactured to tight tolerances for seating and torque retention, this bolt is recommended whenever the head is removed.
