Klein Tools 57032 6-Piece 5-40 In-Lb Micro-Adjustable Torque Screwdriver Set

The Klein Tools 57032 is an adjustable torque-limiting hand driver set covering a 5 to 40 in-lb (0.6 to 4.5 Nm) calibrated range for precision electrical terminal torquing. Built with a lightweight black anodized aluminum body and a tri-lobular textured grip, this 1.0 lb (16.0 oz) overall assembly includes six 3.5-inch power driver bits along with a 1/4-inch nut driver adapter. Certified to ASME B107.300-2010 standards via an included N.I.S.T. traceable calibration document, this torque-sensing instrument prevents over-tightening and terminal thread damage across sensitive breaker panels, commercial meters, and electronic control assemblies.

Best Used For:

  • Circuit Breaker & Panel Terminal Wiring: Applying exact 5 to 40 in-lb torque values on copper terminal lugs and terminal blocks to meet NEC compliance code.
  • Sensitive Electronics & Control Boards: Torquing delicate relay screws, terminal strips, and circuit board standoffs without stripping threads or cracking plastic casings.
  • Commercial Metering & Automation Servicing: Securing precision hardware on industrial control panels, smart meters, and HVAC sensor units.

Key Performance & Safety Features

  • 5 to 40 In-Lb Calibrated Range: Micro-adjustable scale provides exact torque settings in increments required for low-torque electrical connections.
  • ASME & N.I.S.T. Certified Compliance: Includes a factory N.I.S.T. traceable calibration certificate meeting ASME B107.300-2010 industrial requirements.
  • Tri-Lobular Aluminum Handle: Textured black aluminum handle profile offers superior grip leverage and non-slip control during repetitive turning.
  • 6 Extended Power Bits Included: Comes with 3.5-inch long power driver bits including Phillips (#1, #2), Slotted (3/16", 1/4"), Square (#1, #2), and a 1/4-inch nut driver.
  • Automatic Torque-Limiting Release: Internal mechanical clutch disengages automatically when target torque is reached to eliminate over-torquing.
  • Foam-Lined Blow-Molded Storage Case: Custom foam inserts protect internal clutch calibration against jobsite drops and impact.

Pro-Tip: Always return the torque adjustment collar to its minimum 5 in-lb setting before returning the driver to its foam case. Storing torque screwdrivers under internal spring pressure causes calibration drift, compromising future N.I.S.T. accuracy compliance.
