The Genuine STIHL Collar Stud M8 (Part No. 0000 664 2406) is an OEM replacement bar mounting stud designed to securely attach the guide bar to the crankcase on compatible STIHL chainsaws. Manufactured from hardened steel and precision-machined to STIHL's exact specifications, this collar stud provides a secure mounting point for the guide bar while withstanding the high vibration and heavy loads experienced during professional cutting.
Replacing damaged or worn bar studs helps maintain correct guide bar alignment, ensures proper chain tensioning, and prevents premature wear to the guide bar and clutch cover. Genuine STIHL parts guarantee an exact fit and long service life.
