Description
Overview:
This genuine Stihl counter sunk screw is a precision fastener for Stihl earth augers, engineered to secure components where a flush fit is required. Designed for demanding use on machines such as the BT 106 and BT 120 C, it delivers consistent clamping under vibration and load. The countersunk head sits level with the surface to minimise snagging and interference with guards or moving parts, while the accurately cut thread promotes a firm, repeatable fit. Made from durable metal and built to Stihl's specification, it supports reliable assembly and helps maintain performance of the auger drive and related fittings. Identified by Manufacturer Part Number (MPN) 9064 346 1278, it is a straightforward replacement that restores correct fastening where the original screw has worn, corroded, or been lost.
