Description
Overview:
The Pan Head Self-Tapping Screw IS-P6x18 is a genuine Stihl fastener designed for securing components on handheld power tools. Made from durable steel with a corrosion-resistant finish, it provides a reliable hold in pre-drilled holes by forming its own mating thread. The pan head offers a broad bearing surface for neat seating against covers and housings. Size: 6 mm x 18 mm (0.24 inches x 0.71 inches). This OEM screw is suitable for maintenance and repairs on Stihl machines, including hedge trimmers such as the HS81R and HS81RC. It is intended for use where the original screw has loosened, worn, or been lost, restoring correct clamping and vibration resistance while maintaining manufacturer standards (MPN 9074 478 4420).
Key Features:
- Genuine Stihl part for correct fit and dependable OEM performance
- Steel construction with a corrosion-resistant finish for long service life
