Field service and maintenance fastening applications often require a tool that delivers both torque control and the flexibility to easily adjust to different torque values. The Micro Torque screwdriver is an externally adjustable torque tool that offers different setting options for applications that require more than one torque value. The adjustable torque screwdriver features an external adjustment torque scale, which allows an operator to quickly and accurately adjust the torque setting on the tool as needed for different applications. The Micro Torque screwdriver is ideal for field service or production applications. A single torque driver can cover a wide variety of fastening applications.
The Mountz Micro Torque Screwdriver uses the trusted, reliable cam-over technology. The tool eliminates a fastener or bolt from being under and over tightened. The design action of the cam-over screwdriver is such that when the tool reaches its set torque value the mechanism disengages from the drive thus limiting the torque applied. Inside the screwdriver, a precision radial ball clutch “slips-free” when the set torque is reached preventing under and over tightening. Also, the thrust bearings ensure that the torque setting is independent of any end load applied by the operator. As quality control tool, the torque screwdriver allows any user to deliver precision torque control with confidence regardless of task and operator skill level.
How to Change the Torque Setting & Operate the Adjustable Screwdriver
- To set desired torque on the scale, pull down on the “adjustment ring”.
- A simple twist right or left increases or decreases the torque setting .
- Align the desired torque value on the micrometer scale.
- Once the adjustment ring is released it disengages and prevents incidental torque adjustment from occurring.
- When operating the screwdriver, apply a steady twist.
- When torque is reached, the tool will ‘slip” and automatically reset itself.
Designed and manufactured to meet or exceed the accuracy and repeatability requirements of ISO6789: 2003, Mountz offers various Micro Torque screwdriver models that range from 20 ozf.in to 80 lbf.in. The ergonomically designed torque screwdriver provides operator comfort along with quality control. Manufactured with an anodized aluminum handle, the durable nut driver provides a long service life. Incorporating a pull-down ring to engage the adjustment mechanism, a simple twist of the collar right or left increases or decreases torque respectively, while a precision radial ball clutch and cam allows for automatic resetting.
Routine maintenance and torque calibration are necessary for any torque screwdriver. Always use a torque tester or sensor within the range of the tool. Calibrate torque screwdrivers in the “Peak” mode setting of the torque analyzer.
Using a quality torque screwdriver makes a safer world through accuracy and precision. 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 fastened can vibrate loose and excessive torque can strip threaded fasteners.
