Atlas Copco QMX42-2RT Pneumatic Nutrunner Tool

Atlas Copco QMX42-2RT is an inline electric nutrunner designed for precise, repeatable tightening in automated and manual assembly settings, delivering 20 Nm of torque for consistent fastener results. This model is part of Atlas Copco’s QMX family and is commonly cataloged with an inline drive and a drive shaft length of 6-5/8 inches, aiding compatibility with a range of fixtures and tooling setups. The 6-5/8 in shaft and inline configuration are repeatedly noted across distributor listings, underscoring its use in compact, space-constrained assemblies. Market references indicate the QMX42-2RT has been discontinued by the manufacturer, with remaining stock or refurbished units offered by secondary sellers, which is important for planning replacements or upgrades. Related variants in the same family, such as QMX42-3RTV, illustrate the breadth of torque options available within Atlas Copco’s electronic nutrunner lineup, helping manufacturers select the exact torque profile needed for specific fasteners and process windows. In practical use, this class of tool provides controlled torque, repeatable performance across many cycles, and reduced rework in high-volume production environments, making it suitable for automotive, electronics, appliance, and consumer goods assembly where consistent fastening is critical.
