Description
Overview:
The Self-Tapping Screw 4.2x9.5 for Stihl chainsaws is a Genuine Stihl part designed for reliable fastening in service and repair work.

With a 4.2 mm diameter and 9.5 mm length, it is sized for common assemblies found on Stihl equipment, helping keep guards, covers and small fittings properly secured. Suitable for a range of Stihl machines, including the 084 and 028, it supports safe and consistent performance by maintaining correct fitment of parts. This is a practical replacement to keep in the workshop for routine maintenance or when replacing missing or worn fasteners.
