The flange on this screw spreads clamping load over a wider bearing surface than a standard pan-head screw, reducing the risk of the head sinking into or cracking the surrounding plastic over repeated tightening. The self-tapping thread is cut to a pitch and depth matched to the original moulded thread in the housing — a generic M5 screw with a slightly different pitch can cross-thread on the first reinstallation and strip the housing on the second, turning a 50p part into a cracked cover.\u003c\/p\u003e\n\u003cp\u003eThis is particularly relevant for workshops and fleet operators. Because this single part number covers such a broad range of machine families — brushcutters, hedge trimmers, pole pruners, blowers, multi-tool powerheads and cut-off saws — it's a sensible item to keep a small stock of for routine servicing, since covers and starter housings are removed and refitted repeatedly over a machine's working life and these are among the most commonly lost or stripped fasteners during servicing.\u003c\/p\u003e\n\n\u003ch2\u003eFits Models\u003c\/h2\u003e\n\u003cp\u003eThis screw is compatible with the following STIHL models, grouped by machine type.

Genuine STIHL fasteners are matched to the original housing thread to avoid cross-threading or stripping plastic components.\u003c\/p\u003e\n\n\u003ch3\u003eShould I order more than one?\u003c\/h3\u003e\n\u003cp\u003eSince this fastener is used across so many STIHL models and is commonly lost or stripped during servicing, workshops and fleet operators often keep a small stock on hand.
