Atlas Copco 4230 1901 80 QXT 38-050 QMX42-5RT Nutrunner

Atlas Copco QMX42-5RT Nutrunner is an electric 1/2‑inch‑drive nutrunner built around Atlas Copco’s 4230 motor‑unit family, configured as 4230‑1901‑80 with the front-end module QMX42. The package includes a QPT38‑050 transducer set (often listed as QXT 38‑050 in catalogs) and the QM.42 socket holder, delivering integrated torque feedback for repeatable tightening. The 4230‑1901‑80 designation and the QMX42 front end are documented in Atlas Copco dimension drawings and distributor listings for the QMX42 family, confirming compatibility with Atlas Copco’s transducer‑based torque‑control ecosystem. This tool is used for torque‑controlled fastening in automotive, electronics, and general manufacturing applications where a reliable 1/2" drive is required for consistent, high‑quality assemblies.
