Frequently Asked Questions

What's the difference between the J6062C, J6064C, J6014C, and J6006C ratchet head micrometer torque wrenches?

These Proto ratchet head micrometer torque wrenches differ in drive size and torque range:

  • J6062C: 1/4" drive, 40-200 in/lb range
  • J6064C: 3/8" drive, 40-200 in/lb range
  • J6006C: 3/8" drive, 16-80 ft/lb range
  • J6014C: 1/2" drive, 50-250 ft/lb range
  • J6020AB: 3/4" drive, 120-600 ft/lb range

What is a torque multiplier and when should I use one?

Torque multipliers like the J6202A and J6232 amplify input torque by a specific ratio, allowing the user to apply higher torque values with less input force. This all happens without changing its speed. They're ideal for high-torque applications where additional leverage is needed.

Are all PROTO tools covered by the lifetime warranty?

  • Die Grinders, Torque Wrenches, Torque Multipliers, and Torque Testers: 1-year warranty
  • Air Impact Tools: 2-year warranty
  • Torque tool calibration: 90-day warranty
