Description
Overview:
The Spline Screw IS-M5x23-12.9 is a genuine Stihl fastener designed for secure assembly on selected Stihl machines, including the MS 241 C chainsaw and FS 230 brushcutter. Manufactured from high-tensile 12.9-grade steel, it offers strong clamping force and long service life in high-vibration environments. The internal spline drive provides positive engagement with the matching driver for controlled tightening and reduced risk of cam-out. Its size is M5 x 23 mm (approximately 0.20 in diameter x 0.91 in length), making it suitable for factory threaded locations that specify this exact fixing. Ideal as a like-for-like replacement during maintenance or repairs, it helps keep your equipment reliable and safe to use.
