The MTWD is a digital torque wrench that provides a digital display of torque readings. The tool is designed for screw tightening, fastener audit and general torque measurement and provides a visual, acoustic and sensory signal (handle vibrates) when the pre-set torque is reached.

The user-friendly MTWD digital torque wrench is a simple to use and displays real time torque values. The wrench offers four units of torque measurement: N.m, lbf.ft, lbf.in, kgf.m. Simply pre-set the desired torque value and apply force until the green LED illuminates and the handle vibrates. Great for light industrial, automotive, electronics and aircraft applications. Perfect for noisy environments.

The MTWD digital wrench is designed for an operator to easily program a pre-set torque value. The operator can set the tolerance parameters for the digital torque wrench to control the Go and No-Go response signal. The operator sets a lower and upper torque thresholds to get a visual, audible and sensory warning signals when the pre-set torque limits are reached or breached during operation. This function is primarily used for safety and quality control.

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.

To help ensure that you achieve the torque accuracy required of your application, it is important to select a power tool with low scatter and low mean shift. Joint stiffness varies, so it’s necessary to make an allowance for it to achieve the proper torque.

Fitting screws into steel without interlining components is one example of a hard joint with rapid tightening. For this application, the power tool needs to have a quick clutch that interrupts the torque at the pre-set level.

Another example is a soft joint with gaskets and washers, or a long screw, requires a electric screwdriver or pneumatic screwdriver with a strong motor to attain short tightening times.

If there are subsidence or plastic deformations in the joint, then you should opt for a clutch type power tool or a tool with a hydraulic pulse mechanism. The joint would then have time to settle as you are assembling.

Joints with self-locking elements in the thread or clamped nuts are becoming increasingly common. If you work with joints like this, we recommend a screwdriver with a shut-off clutch.

To fully utilize the high performance of a quality power tool, it’s important to know the demands made on the power tool by different screwed joints. Here are some examples that will help you select the kind of power tool you require.

Machine Screw – Hard Joint
Low resistance to turning until the screw head reaches its seating, after which resistance rapidly increases. For rapid screwdriving with moderate torque accuracy choose a high speed tool. For close torque limit or when the quality of thread is uneven, choose a lower speed tool. This is also recommended for brittle material. The most suitable clutch is a shut-off type. An alternative choice is a slip type.

Machine Screw – Soft Joint
Low resistance to turning until the screw head reaches its seating, after which resistance slowly increases. A slower and more powerful torque tool should be used to seat the fastener properly to minimize relaxation in the joint. Most suitable clutches: Shut-off type. Slip type possible.

The TB is small preset production torque wrench with a fixed head. The versatile wrench is available with different head configuration options, like open, box, flare, hex key and ratchet head. TB models are designed to have one permanent head style attached to it. When the TB torque wrench achieves torque, the head breaks-over signaling to the operator to stop applying torque to the fastener or bolt.

Break-Over torque wrenches are essential to limiting the amount of torque applied to an assembly or fastening. Break-over torque wrenches, typically deflect 20-90 degrees on torque delivery, thus indicating torque has been reached. Many break-over wrenches require manual resetting, while others have an automatic resetting feature.

The slim TB torque wrench is a pre-set tool that offers a tamper-proof internal torque adjustment setting. There is no external adjustment scale, so the wrench must be preset using a torque tester. Small and lightweight, the TB wrench is ideal for applications with limited space. Mountz offers various TB wrench models covering a torque range of 25 inch-ounces up to 50 inch-pounds.

A pre-set torque wrench is similar to a person setting an alarm clock to signal the achievement of a selected time. The torque wrench is pre-set to the required torque value of the application and then the tool signals the operator when torque is achieved.

Designed and manufactured to meet or exceed the accuracy and repeatability requirements of ISO6789: 2003, Mountz offers the TB wrench in six different colored aluminum handle options, which allows production areas to color-code specific torque values for various fastening applications.

The correct tightening of SMA connectors used in RF cabling applications is essential to ensure optimum performance. The TB torque wrench is commonly used in these applications. Break-Over Wrenches are essential to limiting the amount of torque applied during the assembly process.
