Description
Overview:
The Spline Screw IS‐M4x12 is a genuine Stihl fastener designed for secure, repeatable fixing in high‐vibration tools such as the TS 440 and TS 480i disc cutters. Made from robust steel with an internal spline drive, it offers reliable torque transfer and long service life when carrying out repairs or routine servicing. Its M4 x 12 mm sizing makes it suitable for precise locations across Stihl machinery where a compact machine screw is required. Common uses include securing covers, housings, guards and other assemblies where accurate alignment and holding strength are important. As an OEM component, it matches the original specification to help maintain equipment performance and safety.
