What This Part Does
The 3862463 is a genuine Volvo Penta OEM fastening nut used in the throttle body assembly within the inlet and exhaust system on selected Volvo Penta gasoline marine engines. It secures throttle-body hardware at the specific diagram position where this part number is called out. Small fasteners like this are integral to maintaining correct throttle-body component alignment and clamping — and the correct OEM number ensures the right thread specification and material for the application.
Compatible Applications
- Selected Volvo Penta gasoline marine engines using throttle-body inlet and exhaust assemblies where part number 3862463 is specified
Fitment is by exact diagram position rather than a broad engine-family matrix. The safest confirmation is a serial-number-based Volvo Penta parts diagram showing 3862463 at the correct throttle-body hardware location for your specific engine.
Serial Number Fitment Notice
Locate the engine data plate for your model and serial number and cross-reference against the Volvo Penta inlet and exhaust parts diagram before ordering. Gasoline engine throttle-body assemblies can use similar-looking fasteners at different positions — confirming the part number in the diagram is the most reliable check.
When to Replace
- Original nut is corroded, rounded, or thread-damaged
- Fastener no longer torques correctly or pulls free from the stud
- Throttle-body service requires fastener removal and original shows visible wear
- Inlet or exhaust service disturbs the throttle-body hardware stack
Installation Notes
Confirm the replacement nut against the exact Volvo Penta diagram position before installation. Inspect the corresponding stud, washers, and surrounding throttle-body hardware while the assembly is accessible. Tighten to the Volvo Penta service torque specification for the inlet and exhaust assembly on your engine model. Do not substitute by thread size or wrench size alone — the OEM number ensures the correct specification for this specific application.
Technical FAQ
Q: Is this a standard metric nut or a Volvo Penta-specific fastener?
A: While it may share a common thread form, this is an OEM Volvo Penta part specified for the throttle-body assembly at a defined diagram position. Substituting by thread size alone risks incorrect material grade or fit for this application.
Q: Is there a superseding part number for 3862463?
A: No confirmed superseding number has been identified. Order directly as 3862463.
Q: How many nuts does the assembly require?
A: Confirm the quantity from the Volvo Penta parts diagram for your specific engine serial number — throttle-body hardware quantities vary by assembly version.

Parts Desk Insights
Small OEM fasteners like this one come up most often during throttle-body or inlet service when the original nut is corroded or rounded off during removal. The most common mistake is trying to source a generic substitute by thread size — for throttle-body hardware specifically, using the correct OEM fastener keeps the assembly torquing correctly and prevents problems on reassembly. If the nut came off in pieces or stripped the stud, inspect the stud condition before reinstalling anything new.
