Description
Overview:
This Collar Nut M12 x 1.5 with left-hand (L/H) thread is a genuine Stihl fastener designed for securing cutting attachments and related components on heavy-duty brushcutters such as the Stihl FS460C and FS240. Built from durable metal to handle vibration and high loads, it keeps assemblies firmly in place during demanding cutting work. The left-hand thread matches the reverse-rotation spindle used on many Stihl gearboxes, helping prevent loosening in use. It is a straightforward, like-for-like replacement for worn or damaged nuts, supporting safe operation and consistent performance. As an OEM Stihl part, it offers the correct fit and thread engagement on compatible machines, making it suitable for professional landscapers, grounds teams, and informed DIY users.
