| Question | Answer |
|---|---|
| Is 102021 the same as any generic 3/8-16 nut? | While the thread is 3/8-16, this is an OEM Graco part. For critical assemblies, using the specified OEM hardware helps maintain fit and durability. |
| How do I confirm it fits my sprayer or pump? | Check your unit’s parts manual or exploded diagram. If the bill of materials lists 102021 at the hardware location you’re servicing, it’s the correct nut. |
| Where is it typically used? | Commonly on pump frames, elevator/mounting brackets, and tie-rod ends in systems like Viscount I 1000 and SaniForce elevator kits. |
| Do I need threadlocker? | Follow the service manual. Many mounting points rely on torque spec alone; some applications may call for a medium threadlocker. Do not exceed specified torque. |
| What if my manual lists a different finish or grade? | Use the exact specification in your manual. If grade/finish differs, select the OEM equivalent to ensure proper clamping and corrosion resistance. |
