The STIHL 19mm Combination Wrench / Scrench (Part Number: 1124-890-3400) is a genuine OEM compact service tool engineered specifically for STIHL chainsaws equipped with full-wrap handle assemblies. Featuring a shortened profile ("shorty" design) and a integrated 19mm socket and flathead screwdriver blade, this tool provides maximum clearance to access spark plugs, bar nuts, and chain tensioning screws without binding against oversized wrap-around handles.
- Genuine STIHL OEM Service Tool: Factory replacement part (Part # 1124-890-3400 / 1124 890 3400 / replaces 1119-890-3400) built for precise fitment and long service life.

- Commercial-Grade Steel: Heat-treated, heavy-duty alloy steel construction designed to handle field torque without rounding socket heads or bending the blade.
- Broad Professional Compatibility: Designed for mid-to-large STIHL professional chainsaws, including MS 361, MS 441, MS 650, MS 660, 066, and related wrap-handle configurations.
