Experience, Quality and Reliable
In the manufacturing and assembly world, tightening, controlling, or measuring torque fasteners is imperative for production efficiency. An inadequately torqued fastener can vibrate or work loose: conversely, if the tension is too high, the fastener can snap or strip its threads. Faced with these problems, manufacturers are realizing that precise torque control can spell the difference between a safe, reliable, and economical product and complete disaster.

Anybody who has to tighten a threaded fastener and needs to control, monitor, or measure torque needs sophisticated torque tools. If manufacturers want to save money, make their workplace safer, enhance product quality, or reduce their exposure to liability; only specialized high-quality torque tools will get the job done properly.

1. Pick the Right Torque Tool
A wide variety of torque tools are available to control or measure the torque applied to fasteners, from electric screwdrivers to large industrial torque wrenches, torque analyzers, torque sensors, pneumatic screwdrivers and torque multipliers. These tools utilize calibrated torque setting mechanisms that may be factory pre-set or user-definable. When the specified setting is reached, the tool gives a visual, audible, or tactile signal. The anticipated production output, the type of materials being joined, the amount of torque required, and the specified fasteners determine the selection of tools for a given application. Lighter materials such as wood or plastic may require only lightweight tools; likewise, heavy materials such as steel may require stronger or larger tools. If torque data must be gathered during the assembly process or quality process, tools should also have connection ports such as USB, RS-232 and other cabling connections.

2. Establish a Torque Calibration Program
Calibration is fine-tuning the torque control process in a production environment. Torque calibration should be checked periodically to determine whether torque tools are operating at their proper settings. Many tools don’t have a locking device, and users may easily change their torque settings. When this happens, the tool falls out of adjustment.

A regularly scheduled calibration program enables quality control personnel to correct divergence from proper settings, whether it’s because of normal slippage over time or because of adjustments to the tool. Begin by setting a calibration interval initially based on severity of the application and the tool manufacturer’s recommendations. If the applied torque values are out of range, cut the calibration interval in half and re-test the tools.

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.

Mountz, Inc., a specialist in the design and manufacture of torque control products, offers the LPX torque sensor for testing small torque tools. The LPX is a low torque sensor designed for calibrating and testing small hand screwdrivers, torque wrenches and power tools. With it’s with low profile design, the calibration instrument can be used for automated applications, by mounting it to a palletized system. This saves time as there is need to remove the driver from the robot or off the automated system for calibration. These versatile torque sensor is used in conjunction with a torque tester. Mountz offers various LPX models covering a torque range from 1 inch-ounce up to 20 inch-pounds.

Using a quality torque sensor and torque tester has become increasingly important for many companies to ensure that proper torque is being applied. Testing torque is a science and not something that can be left to chance.

Torque tools go out of calibration with use. Calibrating a torque tool is a fine-tuning process of bringing the tool back within its tolerance. Torque testers can also be used for quick tools tests on the line or in the lab to determine whether torque tools are holding a given setting.

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.

The TorqueLab® LTT is a laboratory grade instrument designed for testing and monitoring torque applications and is commonly used for quality control, R&D and calibration applications. As an advanced torque controlling, monitoring and documentation solution, LTT torque tester is used for testing or calibrating hand torque screwdrivers, electric screwdrivers, pneumatic screwdrivers, torque tools as well as a torque wrench calibration. The LTT torque analyzer features the EZ-Plug & Play technology, which is an auto-recognition system with Mountz torque sensors.

The Loading Bench by Mountz Inc. is a laboratory grade instrument designed to enable accurate torque wrench calibration with less physical effort. The Loading Bench simulates torque application conditions with minimum effort and enhanced safety for the calibration technician assuring a more accurate calibration. The calibration instrument enables quick and easy torque wrench calibration and presetting, independent of human influence or transducer side and end load factors. The Mountz Inc. Loading Bench is designed to calibrate torque wrenches in accordance with International Standards ISO6789:2007.

Calibrating a torque wrench is a fine-tuning process of bringing the torque wrench back within its tolerance. The international standard for torque wrench calibration (ISO6789) mandates all conforming wrenches meet or exceed 5,000 cycles before requiring calibration. The drive system of the Loading Bench assures the load application eliminates potential operator induced test errors. Built for durable use, the Loading Bench reduces the operator effort required to attain and sustain torque during the calibration process.
