Description
Overview:
The Spline Screw IS-M5x25 is a genuine Stihl fastening screw for securing components on hedge trimmers and long-reach hedge trimmers, including the HS81R and HS81RC. Made from durable metal with an internal spline drive, it provides positive driver engagement for controlled tightening. Its M5 thread and 25 mm length (M5x25) match original specifications for a reliable, repeatable fit where specified by Stihl. Used across housings, gearcases, handles and linkage parts, it helps maintain safe operation and prevents looseness under vibration. Manufactured to OEM standards, and supplied under part number 4237 716 0400, it is suitable for routine maintenance and repair tasks on a wide range of compatible Stihl machines.
Key Features:
- Genuine Stihl OEM fastener for assured compatibility and fit
- Metric M5 x 25 mm sizing to replace the original without modification
- Internal spline (star-type) drive for secure grip and reduced cam-out
- Durable metal construction designed for long service life
- Holds fast under vibration when tightened to specification
- Clean, accurate threads help reduce the risk of cross-threading
- Widely used across Stihl hedge trimmers and long-reach hedge trimmers
- Simple to install with the correct spline driver
Typical Applications:
Replacing worn, missing or damaged screws on Stihl hedge trimmers and long-reach hedge trimmers. Commonly used on gearbox covers, handle frames, blade frames and guards, linkage assemblies and other service points during blade changes, gearbox work, or general strip-down and reassembly.
