Overview:
The Pan Head Self-Tapping Screw is a genuine Stihl OEM fastener for chainsaw assembly and repair. Made from durable steel with a smooth pan head, it provides a secure, tidy clamp on covers and housings without damaging surrounding material. Its self-tapping thread is designed to cut its own mating thread in softer substrates such as plastics or thin metals commonly found on chainsaw bodywork. This screw is specified for Stihl machines including the MS 311 and MS 391, helping maintain factory-fit integrity during maintenance. OEM/MPN references include 9074 477 4448 and 90744774448, ensuring you can match it to service documentation and parts diagrams with confidence. It is a reliable choice for restoring secure fixings where originals have worn, been lost, or require replacement.
