Genuine Parts
Cummins 3058686 Bolt
- Engine Compatibility : Primarily used on heavy-duty diesel engines, including non-certified 14-liter N14 Cummins series engines, as well as various industrial and commercial vehicle platforms.
- Design & Head Style : Features a 12-point flange head, which provides greater surface contact area for sockets and wrenches compared to a standard 6-point bolt. This allows for higher torque application while reducing the risk of tool slippage or rounding off the bolt head during installation or service.
- Function : Serves as a high-strength structural fastener used to secure critical engine assemblies, housings, or internal components subject to severe vibration, heat, and mechanical stress.
- Dimensions : Standard size specifications are 3/8″-16 thread pitch with a length of 2-1/8 inches.
The Cummins 3058686 bolt (often updated under part number 3058686-20) is a genuine OEM twelve-point cap screw/bolt designed for heavy-duty diesel engines.
