Description
Overview:
This is a genuine Stihl self-tapping screw for lawn and garden machinery, used to secure covers, brackets and structural components on mowers and ride‐on tractors. Made from high-strength steel, it forms its own thread in a prepared hole for a tight, reliable hold. The size is IS-P4x16-10.9, suitable for many OEM assembly points on Stihl equipment. It is commonly found on walk‐behind and ride‐on models, including the RM 655.0 VS and RM 655.0 RS. By matching the original specification, this screw helps maintain correct fit and finish, resists vibration in service, and supports long-term durability of the machine. Manufacturer reference: 9104 003 8734 (also 91040038734). Genuine Stihl part.
