Description
Overview:
This clamping ring is a genuine Stihl OEM fastener used to secure components on selected hedge trimmers and ride‐on machines. Made from durable metal with a resilient spring action, it holds parts firmly in place to prevent movement or vibration during use. It is engineered for an accurate fit on Stihl tools, helping maintain smooth operation and reliability over time. Ideal as a like‐for‐like replacement when the original ring shows wear, deformation, or loss of tension. Designed for Stihl HSE61 and HSE71 hedge trimmers, it also appears in several other Stihl platforms where a compact retaining ring is specified.
Key Features:
- Genuine Stihl part for assured compatibility and fit
- Durable metal construction resists wear and maintains clamping force
- Helps keep guards, housings, sleeves, or linkage points securely fastened
- Supports smooth operation by reducing loosening from vibration
- Sized to Stihl specifications-no modification required
- Quick to install with basic hand tools, minimising downtime
- Suitable for routine maintenance or preventative replacement
- Reliable performance in both residential and professional use
Typical Applications:
Used to retain and secure small assemblies on Stihl hedge trimmers and selected lawn and garden equipment. Commonly applied where a compact clamp is needed around a shaft, sleeve, or housing interface. Useful when refurbishing machines, after impact damage, or during scheduled servicing to restore correct clamping and reduce the risk of parts loosening in operation.
