Description
Overview:
The Spline Screw IS-M5x94x20 is a genuine Stihl OEM fastener designed for FH and HL series Kombi tools, including the FH 75 and HL 100. It is a precision steel screw with an internal spline drive for secure, slip-resistant fastening. Used to hold key assemblies in place, it helps maintain alignment and reliability in long-reach hedge trimmers and related attachments. Dimensions are M5 thread with a 94 mm length and 20 mm section; for reference this is approximately 3.70 in x 0.79 in (94 mm ≈ 3.70 in; 20 mm ≈ 0.79 in). Built for routine servicing and repair, this screw restores correct fit where the original has worn, corroded, or been lost. As a genuine part, it matches factory specification for fit and performance.
