Description
Overview:
The Spline Screw IS-M4x10-8.8 is a genuine Stihl fastener designed for securing assemblies on selected chainsaws and power tools. Made from property class 8.8 hardened steel for dependable strength, it features an internal spline drive for positive tool engagement in vibration-prone applications. The size is M4 x 10 mm (approximately 0.16 x 0.39 inches). Specified by Stihl for models such as the MS 382 and MS 461, it is also used across other compatible machines listed below. This screw helps maintain correct clamping force on covers, brackets and housings so your machine operates reliably. Supplied to Stihl OEM No. 9022 313 0651 for straightforward identification and like-for-like replacement. Its short 10 mm length helps prevent bottoming in blind holes, while precision threads support consistent torque settings during servicing.
