Torque Management & Cost Control

Sound torque management leads directly to measurable profit improvement.

The relationship between sound torque management practices and profitability in assembly operations proves itself repeatedly in thousands of plants every month. Products assembled with threaded fasteners are dependent upon appropriate torque management for product quality. Optimizing the process vastly reduces all categories of nonconformance costs and the savings go directly to your bottom line. Not as readily measurable, but of equal or even greater impact, is the increased level of customer satisfaction that affects our product image, brand name, and sales volume.

Regardless of the term you choose – “Error-Proofing” or “Poka-Yoke” or “Robust Process” – the process objectives remain the same. The fastener tightening process must be as close to immune to error as possible, while retaining high throughput rates.

Torque management systems and equipment have made incredible advancements in this area in the last five years. In fact, the pace of change has been revolutionary. This diversity of new systems and equipment permits optimizing your process for quality, while sustaining or increasing throughput leading to remarkable ROI’s for your investment.

The chart above is typical of the experience of our customers who have invested in optimizing their torque management. Decreases of 50% – 90% in internal and external nonconformance costs are frequently the result when appropriate torque management systems are designed and implemented.

The Torque Management Pyramid graph is provided as a tool to assist you in developing your thoughts about your current process, and how that process might be managed to improve profitability.

Torque Calibration Systems

Torque Tools and Power Tools

Ensuring that the tools used to apply torque and those used for auditing have been properly calibrated and remain in calibration is the foundation of every torque program. “Best practice” for today’s programs includes a two-step system of certifying and regularly checking each tool.

The first step in a “Best practice” system is certifying tools, which would typically require test equipment of the highest accuracy and the use of mechanical loaders. Often the capability of testing a wide range of tools in necessary. The use of multiple sensors with a single test device, such as the PTM or System 5 with a mechanical loader, is the generally the most cost effective alternative for certifying tools.

The second step is the regular checking of tools, usually performed by the user of the tool. The tester used for this purpose would require simplicity of operation, ease of use and be readily accessible. Not surprisingly the cost and durability are significant factors when purchasing testers for this application. Torq-Tronics and VeriTorq have been designed to meet the needs of this user and the purchasing department.
