Description
Overview:
The Spline Screw IS‐M6x25 is a genuine Stihl fastener for professional chainsaws such as the 066 and MS 650. Made from durable steel and precision‐machined for a consistent fit, it secures key assemblies and helps maintain alignment under vibration. The IS (internal spline) drive provides positive tool engagement, reducing the risk of slippage during tightening and removal. Its metric size is M6 x 25 mm (6 mm diameter x 25 mm length), which is approximately 0.24 in x 0.98 in, making it a direct replacement where an M6 fixing of this length is specified. Supplied to Stihl specification, this screw supports reliable maintenance and repair work, helping keep your saw performing safely and efficiently in demanding conditions.
