Description
Overview:
The Pan Head Self‐Tapping Screw IS D4x8 is a genuine Stihl fastener for securing covers, housings and guards on a wide range of Stihl garden and construction tools. Sized D4x8 (4 mm diameter x 8 mm length), it is made from durable steel and forms its own thread in suitable materials for a firm, vibration‐resistant hold. The pan head provides a broad bearing surface that seats neatly against plastic or metal components. This screw is commonly used on cordless hedge trimmers such as the HSA 56 and HSA 66, and across other compatible Stihl models. Supplied as a Genuine Stihl Part under MPN 9075 478 0630, it is suitable for both assembly and day‐to‐day maintenance tasks.
