A dial indicating torque screwdriver is designed for torque evaluation and torque verification. It is a low cost tool that can utilized for QC, R & D and assembly operations. The Mountz dial indicating torque screwdriver can be used to monitor torque as it increases or decreases or display peak torque applied. The dial torque screwdrivers, by Mountz, measure torque through the use of known twisting force needed to distort a torsion bar. The amount of torque applied is measured on a dual scale dial display. This tool can be used in two ways, it can either be set in track mode so it can constantly track the applied torque or set in memory mode, which is done by withdrawing the slider and resetting the bezel ring to zero before using. This tracks the applied torque as before, but leaves the memory pointer at the maximum torque position.

Determine Torque Requirements in R & D
When determining correct torque specifications, the engineer must consider the maximum load placed on the fastener, the strength of the material joined, and whether the joint is hard or soft. A hard joint connects materials directly. In this case, the fastener rotates very few degrees to develop full clamping force after it encounters the material. Since a soft joint contains a gasket or involves compressible materials, it requires additional tightening after the fastener makes contact, to achieve full clamping force.

One recognized method is to perform a destructive test with a calibrated torque control tool on the actual material and fastener to be joined. An evaluation is usually conducted with ten parts, ten fasteners, and a calibrated torque control tool with a transducer. First the fastener is tightened to the point of failure, then repeated several times to verify the consistency of the failure point. Now another series of tests is begun whereby the joint is torqued to 75% of the failure point. Depending on how the parts will be used, the tightening can be reduced by any degree necessary. If parts on a machine are subject to heavy vibration, maybe 85% of the total force is necessary for good torque control.

Small torque tools go out of calibration with use. To maintain consistent accuracy, small torque tools must be checked periodically for wear or defective parts. A small power or hand torque tool is a measuring tool that must be properly calibrated and maintained.

The easy-to-use EZ-TorQ digital torque tester is ideal for all small hand torque and non-impacting torque power tools. The small size and portability of the torque tester makes it ideal for checking torque tools on production floor daily or weekly to ensure the tools aren’t falling out of calibration. The concept of torque validation is a central theme in every successful quality assurance program.

As a torque controlling, monitoring and documentation solution, the EZ-TorQ II enables operators and engineers to ensure product quality, safety and reliability promptly on the production floor. The EZ-TorQ II can calibrate hand torque screwdrivers and wrenches as well as power tools to avoid over tightening problems such as stripped fasteners and parts, under or over torque tightening problems, which can increase liability and risk of recall.

A regular torque tool calibration and re-calibration guarantees the operator repeatable accuracy and adherence to international standards. Torque testing also ensures torque equipment is operating to peak performance and can highlight potential tooling problems before they arise perhaps due to tool wear or broken components.

A brushless rotary torque sensor is a finely tuned instrument designed for monitoring and testing torque applications where accuracy and reliability rank paramount. Designed for torque evaluation and verification, the brushless rotary torque sensor is a laboratory grade instrument that is commonly used for quality control, R&D and calibration applications.

For use with most power tools, high RPM tools, or rotational torque measurement applications, a brushless rotary torque sensor provides a higher level of accuracy over other standard rotary torque sensors. By connecting a brushless rotary torque sensor between an electric or pneumatic tool and an assembly application, you can monitor the torque being applied from the tool to a fastener or bolt. The torque sensor plugs into a torque tester or torque meter to display and capture the torque readings.

This special class of torque sensor is particularly valuable for measuring torque on pulse tools with strong vibrations. When using a standard rotary torque sensor for testing a pulse tool, there is a common “brush bounce” that plagues the testing accuracy. A brushless rotary torque sensor solves that issue and delivers consistently accurate readings ? whereas brushes within standard rotary torque sensors can bounce on the armature slip rings, which can impact the accuracy of the torque readings.

The TorqueMate is a microprocessor controlled digital torque wrench. Featuring a large LED screen, the digital torque wrench enhances process reliability through complete monitoring of the fastening and assembly process with full data collection of the measured values. The efficiency and manufacturing cost-savings that the TorqueMate provides, will ultimately translate into more products shipped quickly, with fewer defects.

The TorqueMate digital wrench can be used for torque calibration, joint testing, auditing or verification of torque applied. Designed for R&D, Quality Control, a lab, and maintenance or production areas the wrench is ideal for testing and storing torque measurement data for ISO, SPC and QC documentation. The user-friendly interface makes it quick and simple to setup torque testing and auditing parameters.

Controlling torque is essential for companies to ensure their product’s quality, safety and reliability isn’t compromised. The failure of a three-cent fastener that isn’t properly tightened can lead to catastrophic or latent failures. Fasteners that are insufficiently torqued can vibrate loose and excessive torque can strip threaded fasteners. Using a quality digital torque wrench has become increasingly important for many companies to ensure that proper torque is being applied and maintains gauge requirements associated with the ISO 9001 Quality Standard.
