Atlas Copco QMX42-5RT Pneumatic Nutrunner Tool

The Atlas Copco QMX42-5RT electric nutrunner is a compact, 1/2 in drive tightening tool designed for precise bolt fastening in manual or semi-automatic assembly lines. It delivers 10–50 Nm of torque with a 21.3:1 gear ratio and accepts standard 1/2 in sockets, enabling repeatable tightening across small to medium fasteners. Weighing 7.5 lb and measuring 22 in long by 4 in wide by 2 in tall, the QMX42-5RT belongs to Atlas Copco's QMX family and carries catalog identifiers such as 8432513010. This model is designed for durable, high-precision performance in constrained workspaces where controlled torque is critical, supporting reliable fastener integrity in manufacturing and maintenance tasks. In addition to its fixed torque range, the tool's compact form and 1/2 in drive make it suitable for integration into manual tooling stations or robotic-assisted assemblies that require quick bit changes and consistent results.
