Description
Overview:
The Washer 10.5 for Stihl RT 5112.0 Z and RT 6112.0 ZL mowers is a genuine Stihl metal washer designed to secure fasteners and spread load evenly across mating surfaces. Precision made to Stihl specification, it helps keep assemblies tight under vibration, supporting reliable mower operation. The "10.5" denotes an inner hole size of 10.5 mm, commonly paired with M10 fixings used around mowing decks, chassis brackets and controls. Manufactured as a flat, round washer from durable metal, it resists deformation during tightening and service. Supplied as Stihl MPN 9309 021 0200, it is a direct replacement part that fits a wide range of Stihl lawn tractors and walk-behind mowers, including the RT 5112.0 Z and RT 6112.0 ZL.

- 10.5 mm inner diameter for secure seating with common M10 fixings
- Flat, robust metal construction for consistent clamping and load spread

- Versatile use across deck, frame and control linkages on compatible models
- Simple to install with standard tools
Typical Applications:
Used wherever an M10-class fixing needs a stable bearing surface on Stihl mowers and lawn tractors.
