Description
Overview:
The Spline Screw IS‐M4x20 is a genuine Stihl fastener designed for reliable component fixing across a wide range of construction and garden machines.

This OEM screw helps maintain alignment and reduces the risk of loosening under vibration, supporting long service life of your equipment. Ideal for many Stihl tools, including the SP81 and TS460, and supplied under Manufacturer Part Number (MPN) 9022 371 0710.
