Proto Micrometer “Click” Style Torque Wrench

Torque wrenches need to be accurate. Period.  When a wrench tightens a bolt the rotational force -the torque – causes the bolt to stretch as the threads seat tightly against one another.  The trick of the torque wrench is to put enough force on the threads the bolt won’t work loose, however not too much that it risks cracking the metal.  This tolerance range can be quite narrow, and staying within it may be the difference between a smooth running machine and one stopped dead in its tracks.  And, even in some cases it can be a matter of life or death.

Proto knows this and they boast of sparing no effort to make their wrenches the most accurate on the market.

Proto offers an extended amount of professional torque products.  The product line ranges from easy-to-use Micrometer, or “click” style Torque Wrenches, Electronic Torque Wrenches, Dial Torque Wrenches and Torque Screwdrivers to full-featured electronic Torque Multipliers and Torque Testers. Each torque wrench is manufactured in the USA to precise specifications for maximum performance for your torque application.

The Proto Professional quality “click” type precision wrench will tell the user exactly when to stop tightening for exact precision. The positive locking mechanism at the end of the wrench makes it easy to dial and lock in the desired torque.  The spring holds the wrench tang, tilt block and plunger in place until the set torque is reached, after those components snap off center with a click that the user can hear and feel.   The spring is vital to the wrench; if the spring is too worn it can throw the entire system out of calibration.  Proto goes to great lengths to ensure quality of their springs over tens of thousands of uses.

Proto Click Style Torque Wrenches are calibrated to ±3% of torque reading clockwise and ±6% of torque reading counterclockwise at 20% to 100% of full scale.  All Proto Click Style Torque Wrenchs are Calibration Certified to ensure actual readings and include a unique torque wrench serial number.  Moreover, Proto Torque Wrenches are certified to meet, or exceed, the standards specified in ANSI B107.14-1994.  Meaning, they are one of the only tools used in the aeronautic industry.  Proto offers 1/4″ – 1″ drive in both ratchet and fixed head styles, covering torque ranges from 10 in. lb. to an extraordinary 2,000 ft. lb for all tightening needs.  The Proto Click Style Torque Wrenches are for the professionals who need durability and accuracy.
