With fastening applications, controlling the torque by which a screw or bolt is tightened to is essential for controlling the preload. Torque control tightening is one method used by many manufacturers to control the preload of a threaded fastener. An inaccurate tightening method or an improper torque tool being used for an application are key factors that frequently cause fastening failures.
Every day, teams of engineers work together with a common goal to steer clear of fastening failures. To deliver a consistent production of high-quality products. Manufacturing breakdowns lead to product failures, manufacturing downtime, costly rework, plant closures and massive product recalls. Fastening failures will impact the overall quality. Investigating failures in the fastening process is costly and time-consuming.
The process of tightening threaded fasteners is critical for assembly applications. The best way to avoid tightening failures is to select the proper torque tool for the application. Torque tools feature different torque control technologies. Selecting the proper tool for the application is essential. A manual torque tool that utilizes cam-over technology is engineered to prevent fastening failures and ensure proper 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 production 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.
The new TLS Pro series by Mountz is the next generation preset torque screwdriver. These new tools are an upgrade to the reliable and trusted Mountz cam-over torque screwdriver technology. The screwdrivers were engineered to enhance the user experience during the fastening process. The new screwdriver offers the same performance, same quality, same torque results as the old dependable TLS screwdriver. The new modern design of the TLS PRO improves the durability and the ergonomic experience for the assembly operator. Making a safer world through accuracy and precision is the core purpose at Mountz.
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 ensure that the torque setting is independent of any end load applied by the operator. Designed for a variety of industries like electronics, semiconductor, aerospace, communications, medical and other production environments, a Mountz TLS Pro preset screwdriver ensures consistent torque control.
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 0.45 to 120 inch-pounds. Mountz also offers ESD compliant model options.
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.
