Torque Screwdriver

Description

As part of an ongoing Torque Product Line expansion,  Proto has enhanced its Torque Screwdriver offerings. The launch includes more accurate versions of four existing tools and the introduction of four new torque screwdrivers, which boast more accuracy then current Proto versions - a total of eight tools. These tools have been specifically requested by Proto customers, especially those in the electronics and aerospace industries.

The company’s previous offering included four ¼-in. drive Torque Screwdrivers – an inch-ounce model and an inch-pound model with an accuracy range of +/- 6% of the torque reading, as well as a CERT version of each. By re-engineering these with precision-machined internal components, Proto has improved accuracy to a precise +/- 4% of the indicated torque reading. This accuracy level is available in the clockwise direction from 20% to 100% of full scale.
 
In addition, the company has introduced four entirely new 1/4-in. drive Torque Screwdrivers with an impressive +/-2% accuracy (in the clockwise direction from 20% to 100% of full scale). The two new models also include inch-ounce and inch-pound versions.
 
The new Proto Torque Screwdriver line is as follows:

Inch-Ounce Models
 

  • Upgraded: J6104 and J6104CERT: 1/4-in. drive, 20-100 in-oz., calibrated to +/- 4% of torque reading, clockwise, at 20% to 100% of full scale.
  • New: J6104A and J6104ACERT: 1/4-in. drive, 20-100 in-oz., calibrated to +/-2% of torque reading, clockwise at 20% to 100% of full scale.

Inch-Pound Models
 

  • Upgraded: J6106 and J6106CERT: 1/4-in. drive, 7-36 in-lbs., calibrated to +/-4% of torque reading, clockwise, at 20% to 100% of full scale.
  • New: J6106A and J6106ACERT: 1/4-in. drive, 7-36 in-lbs., calibrated to +/-2% of torque reading, clockwise, at 20% to 100% of full scale.

The CERT versions include paperwork that certifies their calibration in accordance with NIST industry standards. This certification is required by some companies that don't have their own calibration labs.
 
Torque settings are easily changed via a metal lock ring allowing micrometer-style adjustments. Each Torque Screwdriver has a ¼-in. square drive tip, and ships with a 1/4-in. square to 1/4-in. hex adapter for use with insert bits. It comes in a blow molded plastic box for protection and easy storage.
