In maintenance and manufacturing applications where consistent and accurate torque control is absolutely necessary, Mountz, Inc. offers the TSC & TSP Cam-Over Torque Wrenches. These torque wrenches are designed to deliver reliable and precise torque control for torque applications that do not tolerate over-torque conditions. Improper torque control increases manufacturing costs and delays. Designed for variety of industries like aerospace, automotive, electronics, energy, medical, and packaging, the TSC & TSP torque wrenches ensure proper torque control.

Built with a cam-over design, the accurate TSC & TSP torque wrenches prevent a fastener or bolt from being over-torqued. The design action of the cam-over torque wrench is such that when the tool reaches its preset torque value the mechanism disengages from the drive thus limiting the torque applied.

To many manufactures, the concept of torque is a mystery. Ask them to describe the physics of torque and you’ll likely meet a blank stare. Cracking open a dictionary won’t help much either. To the layman the definition reads like a foreign language that owes more to mysticism than science. Despite the confusion, proper control of this mysterious force remains a critical component for quality manufacturing and has a direct impact on the bottom line issues like product quality, reliability and safety.

THE IMPORTANCE OF TORQUE CONTROL?
The reliability of machine parts subjected to fluctuating loads and stress depends on the fatigue strength of the materials. A threaded fastener, however, relies upon an elastic interaction between the mating components. Its objective is to clamp parts together with a tension greater than any external force trying to separate them. The bolt then remains under almost constant stress and is immune to fatigue. If the initial bolt tension is too low, the fluctuating load in the shank in much greater and it will quickly fail. Reliability, therefore, depends on correct initial tension and is ensured by specifying and controlling the tightening torque.

In the manufacturing and assembly world, tightening, controlling, or measuring torque on 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,” according to Brad Mountz, President/CEO of Mountz Inc. “Likewise, if OEMs 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.”

The following 10 tips for achieving precision torque control will give OEMs vital information needed to streamline their production processes:

1. Determine Torque Requirements
When determining correct torque specifications, the engineer must consider the maximum load placed on the fastener, the strength of the material joined, and whether the joint is hard or soft. A hard joint connects materials directly. In this case, the fastener rotates very few degrees to develop full clamping force after it encounters the material. Since a soft joint contains a gasket or involves compressible materials, it requires additional tightening after the fastener makes contact, to achieve full clamping force.
