Air nutrunners are the controlled end of pneumatic fastening: the tools that run nuts and bolts at speed and stop at a set torque, where impact wrenches deliver brute loosening power but no control. PartsForMachines supplies air nutrunners as part of the air tool range, alongside the impact wrenches, ratchets and torque tooling that share the fastening bay.
The distinction matters at the joint: an impact wrench hammers a fastener to an unknown tightness, a nutrunner drives it smoothly and disengages at its set torque, typically through a shut-off clutch, which is why production lines, wheel bays and assembly work that must hit specification run nutrunners and leave the final verification to a calibrated torque wrench. Tools sell by torque range, the set point must sit inside it, drive size, free speed, and format, straight, pistol and angle heads covering access, with air consumption and operating pressure listed per tool. Compare lines up candidates side by side, and Ask Simon answers the matching questions, torque range to fastener specification above all.
The discipline that makes nutrunners worth owning is calibration culture: clutch settings verified against a torque measurement, supply pressure regulated and constant, since output tracks pressure, and the final critical-joint check still made with the torque wrench. The Norbar torque ranges listed at PartsForMachines complete exactly that loop.
Impact wrenches, ratchets and the air supply chain sit in the same section. For line and bay fit-outs, contact the team via WhatsApp 07754288583.
