Description
Overview:
The Self-Tapping Screw P4x12 is a Genuine Stihl part (part no. 9104 003 8731) used across a range of Stihl garden and grounds care machines. Made from durable, black-coated steel, it forms its own thread as it is driven, so no pre-drilling is usually required. Its compact size suits housings, covers and handle shells where a reliable hold is needed without cracking plastics or stripping thin metal. The P4x12 size equates to 4 mm x 12 mm (approximately 0.16 in x 0.47 in). Commonly found on hedge trimmers such as HSE61 and HSE71, it helps restore a secure, factory-quality fit when replacing missing or worn fasteners and supports routine maintenance where original hardware needs renewing.
Key Features:
- Genuine Stihl part for assured fit and performance
- Self-tapping thread design reduces or removes the need for pre-drilling
- P4x12 size: 4 mm x 12 mm (approx. 0.16 in x 0.47 in) for compact assemblies
- Black-coated steel for strength and dependable service life
- Forms a clean, secure thread in plastics and thin metal components
- Helps prevent loosening and vibration-related failures when correctly installed
- Suitable for restoring OEM fasteners during repairs and servicing
- Straightforward to install with a suitable driver bit
Typical Applications:
Securing covers, shrouds, switch housings, handle shells, cable clips and guards on Stihl hedge trimmers, lawnmowers, ride-on mowers and related equipment. Useful where a short, self-tapping fastener is required to bite cleanly into plastic or sheet metal without a pilot hole.
