What is quality? In manufacturing, a measure of excellence or a state of being free from defects, deficiencies and significant variations. It is brought about by strict and consistent commitment to certain standards that achieve uniformity of a product in order to satisfy specific customer or user requirements (http://www.businessdictionary.com).
Quality needs consistency. Quality provides a purpose. Quality requires commitment. Quality is a choice. Selecting a quality torque screwdriver that consistently provides accurate torque control for a fastening application is a choice. The challenge for an engineer is selecting the proper tool for the torque application. Is a low price screwdriver worth the gamble? It’s a risk. It’s a choice. It’s your decision.
A fastener inadequately tightened 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. Quality is a choice.
Any manufacturing application that requires a threaded fastener to be tightened needs torque control. The cam-over philosophy of each Mountz hand torque screwdriver prevents a fastener or bolt from being under and over tightened. These torque tools are ideal for fastening applications where over-torque conditions are not tolerated. As a quality control tool, the torque screwdriver allows any user to deliver the correct torque with confidence regardless of task and operator skill level. Making a safer world through accuracy and precision is the core purpose at Mountz.
Preset screwdrivers are typically used for production applications where there is one torque setting required and you need to prevent incidental or operator tampering of the torque setting, while adjustable screwdrivers offer different setting options for torque applications that require more than one torque value.
Preset Torque Screwdrivers
A preset torque screwdriver is similar to a person setting an alarm clock to signal the achievement of a selected time. The torque screwdriver is pre-set to the required torque value of the application and then the tool signals the operator when torque is achieved. A preset torque screwdriver does not feature an external adjustment scale. These tools have internal adjustment mechanism for setting the torque value and must be preset using a torque tester. Preset screwdrivers are typically used for production applications where there is one torque setting required. However, if the torque specification changes or a new project requires a different torque setting, the preset torque screwdriver is still flexible enough that a new torque setting can be set internally using a torque analyzer.
The design action of the cam-over torque screwdriver is such that when the tool reaches its selected torque value the mechanism disengages from the drive thus limiting the torque applied. Also, the thrust bearings insure that the torque setting is independent of any end load applied by the operator. Designed for variety of industries like electronics, semiconductor, aerospace, communications, medical and other production environments, a Mountz preset screwdriver ensures consistent torque control. Quality is a choice.
The radial cam design of the Mountz preset torque screwdriver allows for a smooth cam action with minimal wear on the tool. This provides precision torque control and extends the operating life cycle of the tool before necessary routine tool maintenance is required.
Designed and manufactured to meet or exceed the accuracy and repeatability requirements of ISO6789: 2003, Mountz features various preset screwdriver models that range from 5.7 ozf.in to 120 lbf.in. Offering the most complete array of torque screwdrivers available on the market today, Mountz provides preset screwdrivers in different configurations to accommodate the various torque applications.

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.
