Description
Overview:
The Pan Head Self‐Tapping Screw IS‐P5x25 is a genuine Stihl fastener designed for reliable component securing in chainsaws and other outdoor power equipment. Built with a durable metal (steel) construction, it forms its own thread as it is driven, reducing the need for pre‐drilling in many plastics and thin metals. The pan head provides a broad bearing surface for secure clamping without damaging surrounding material. Sized at 5 mm x 25 mm (approx. 0.20 in x 0.98 in), it is suitable for routine service and repairs on Stihl machines, including the MS 211 and MS 181. Genuine Stihl part number 9074 477 4139 ensures correct fit and consistency for users who need dependable, repeatable fastening in workshop or field conditions.

- Genuine Stihl OEM fastener for precise fit and consistent performance
- Pan head for a wide bearing surface and secure clamping
- Self‐tapping thread for efficient installation in plastics and thin metals, often without pre‐drilling
