Volvo Penta 191844 is a genuine OEM hexagon screw used in Volvo Penta marine propulsion applications. Volvo Penta's own parts catalog identifies 191844 simply as "hexagon screw," and current parts references place it in Volvo Penta driveline and sterndrive-related assemblies rather than as a general-purpose hardware item.
Key Features
- Genuine Volvo Penta OEM part number 191844.
- Official Volvo Penta description: hexagon screw.
- Cataloged for Volvo Penta marine propulsion use, including DPH-D1 / Marine Propulsion references.
- Common aftermarket references list diagram reference number 5 and a listed weight of 0.12 lb.
- Current seller references also associate this part with replacement number 3854685.
Engine Compatibility
Current catalog references tie Volvo Penta 191844 to marine propulsion / sterndrive use, including DPH-D1 schematic references and an exhaust and cooling water inlet exploded-view listing. Because hardware can vary by drive family, housing, and production break, fitment should be treated as assembly-specific rather than assumed across all Volvo Penta models.
Serial Number Fitment Notice
Always confirm 191844 against the exact engine or drive serial number and the correct Volvo Penta parts diagram before ordering. Volvo Penta's shop guidance directs customers to identify the exact engine, shield, or drive when locating the correct parts.
When This Part Needs Replacement
Replace this hexagon screw when the original fastener is corroded, damaged, rounded, stretched, seized, or removed during service and no longer meets proper reuse standards. It is also a smart replacement anytime the related Volvo Penta assembly is apart and the original hardware shows wear or compromised thread condition.
Installation Notes
Install only in the correct matched Volvo Penta location using the proper screw grade, thread engagement, and tightening procedure for the exact assembly. Clean and inspect the threaded hole, confirm the mating components are in good condition, and follow the correct Volvo Penta service documentation for torque and installation sequence on the serial-numbered unit. Volvo Penta provides model-specific support and documentation through its service portal.
Alternate/Superseded Part Numbers
Current parts references reviewed list this part under active Volvo Penta number 191844 and also show replacement linkage to 3854685.
Parts Desk Insight
With Volvo Penta fasteners, the key detail is not only the thread type but the exact assembly they are securing. A screw that looks interchangeable can still differ in length, shoulder, grade, or application, so serial-number verification is the safest way to avoid stripped threads, poor clamp load, or repeat labor during reassembly.
