Universal Tool

Universal Tool UT8961-2NR adjustable clutch angle nut runner

SKU CH-BB04-HV47D

Adjustable clutch angle nut runner with 3/8" square drive and auto shut-off for precision assembly

  • Adjustable clutch delivers precise torque control
  • Auto shut-off prevents fastener over-tightening
  • Rugged steel angle head fits tight spaces
  • Rear exhaust directs air away from workpiece
  • Comfort grip reduces vibration during extended use

Adjustable Clutch Angle Nut Runner

The Universal Tool UT8961-2NR is a pneumatic nut runner built for assembly lines that demand repeatable torque. Its adjustable clutch and automatic shut-off stop the tool the moment the target torque is reached. A 3/8-inch square drive fits standard impact sockets used in high-volume production. The rugged steel angle head measures 1-5/8 inches in overall height for access in tight joints.

Sustained Operation Behaviour

Rear exhaust directs air away from the operator and the workpiece during continuous runs. A built-in suspension bail balances the tool overhead, reducing arm fatigue over long shifts. The comfort grip dampens vibration so torque accuracy holds steady from the first fastener to the last. These features keep cycle times consistent in precision assembly environments.

3/8-Inch Square Drive Constraint

The fixed 3/8-inch square drive determines which sockets and adapters can be used; buyers needing a different drive size must select another model. California Proposition 65 warnings note the presence of chemicals linked to cancer and reproductive harm. No other drive options or torque ranges are offered for this part number.

Questions about this item

How loud is the UT8961-2NR during continuous operation and does the rear exhaust help reduce heat buildup?

The rear exhaust directs air away from the operator and workpiece, lowering perceived noise and preventing heat concentration during extended high-volume assembly runs.

What air supply fittings and hose size must I already have to run this 3/8" square drive nutrunner?

A standard 1/4" NPT inlet fitting and a hose rated for the tool's CFM requirement are needed; the built-in suspension bail also requires an overhead balancer or hook.

Will the adjustable clutch and 1-5/8" rugged steel angle head clear the same fasteners as my older inline shut-off tools?

The compact 1-5/8" angle head reaches tight joints that inline tools cannot, while the adjustable clutch maintains repeatable torque on existing fastener patterns.
