Description
Overview:
The Spline Screw for Stihl MS651 Chainsaw is a genuine Stihl fixing designed for secure, long‐lasting assembly of key components on professional saws. Made from high‐tensile alloy steel to property class 12.9, it delivers strong clamping force and excellent resistance to vibration and shock loads typical in forestry and arborist work. The screw uses an internal spline (star) drive for positive tool engagement and controlled tightening. Its Stihl designation is IS‐M5x30x22‐12.9, with a metric M5 thread and a 30 mm length, ensuring a consistent fit where specified. Built for the MS651 and MS661 series, it helps maintain the integrity of the powerhead and associated fittings during both routine servicing and repairs. OEM/MPN: 9022 373 1070 (90223731070). Genuine Stihl part for assured compatibility.
