Cummins 3017502X Hex Head Bolt

The Cummins 3017502X is a metric hex head bolt engineered for high-stress fastening points on M11, ISM, and QSM series diesel engines. Manufactured from high-tensile alloy steel with a corrosion-resistant finish, this fastener ensures clamping force integrity under thermal cycling and vibration loads typical in heavy-duty commercial vehicle operation. Primary applications include fan hub assembly, bracket mounting, and engine accessory drive fastening. Thread pitch and length conform to Cummins engineering standards for the specified engine platforms. This component serves as a direct replacement for OEM part numbers 3017502 and 3017502X across Xi'an Cummins and joint-venture production lines.
