Check before ordering

  • Measure clearance with the intended impact-rated socket and air connection attached.
  • Confirm the exact model, socket-retention arrangement, included muffler/accessories, warranty terms and delivery with Tend.
  • Check compressor delivery, hose length, couplers and pressure at the tool while operating.
  • Use the vehicle or equipment manufacturer’s specified process for final tightening; the impact is not a calibrated torque wrench.
