Mercury / Quicksilver #10-32 Nut 20110 – Pack of 5
Part Number: 20110 | Service Format: 11-20110 | Thread: #10-32 | Pack Quantity: 5 nuts | GTIN: 745061129559
Genuine Mercury / Quicksilver OEM #10-32 nut used across multiple Mercury Marine throttle, carburetor, linkage, and starter-related assemblies. Mercury parts references list this as 11-20110 with a minimum order quantity of 5, making this pack the right quantity for most carb and linkage service jobs. Because 20110 is a shared hardware number appearing in several assemblies, always confirm the part number and diagram position for your specific application — do not substitute by thread size alone, as Mercury uses several #10-series nuts in adjacent assemblies.

Compatible Applications
Fitment must be confirmed against the Mercury parts diagram for your specific engine model and serial number. Confirm 11-20110 specifically in the diagram — do not select by thread appearance alone.
- Carburetor choke-shutter linkage — choke-shutter-to-carburetor-stud nut
- Carburetor screen hardware — screen-screw nut
- Throttle-linkage assemblies (selected Mercury engines)
- Starter pulley hardware (selected Mercury engines)
- Additional small control and linkage assemblies where 11-20110 appears on the parts diagram
When to Replace
- Threads are stripped, damaged, or will not engage cleanly
- Hex flats are rounded and can no longer be turned with a wrench
- Nut is severely corroded or distorted from overtightening
- Nut goes missing during carburetor, linkage, or starter service — keeping a pack on hand prevents delays
Installation Notes
- Inspect the mating stud or screw for thread damage before installing a new nut
- Tighten to the specification in the Mercury service manual for the exact assembly being serviced — do not use a generic torque value for small hardware
- For carburetor choke-linkage applications: Mercury diagrams show 20110 used as both the choke-shutter-to-stud nut and the screen-screw nut

Parts Desk Insights
Best use case: Pick up a pack of 20110 any time you’re into the carb, choke linkage, or throttle hardware on a Mercury engine. They’re easy to drop and easy to lose, and having five on hand means a small fastener won’t stall a full service job.
Common customer issue: Substituting a generic #10-32 nut from a hardware store. Mercury uses several different #10-series nuts in adjacent linkage positions that can look identical but differ in plating, thread class, and load specification. Using the OEM part number from your diagram is the safest approach — it’s a small cost difference that protects a much larger investment. If you’re unsure which nut your diagram calls for, our parts desk can help you read the position before you order.
