Sturtevant Richmont has redefined the torque measurement industry for nearly a century, blending precision, durability and innovation into its products. Guided by John Reynertson’s leadership, the company has built on a history marked by groundbreaking advancements and a commitment to error-proofing systems that enhance manufacturing processes.

Torque control devices are crucial in securing parts together, even in the face of vibration and external forces. These tools help ensure that fasteners are applied with the correct force, maintaining the assembly’s integrity. However, while torque measurement can confirm that a fastener has been tightened properly, it cannot detect all errors. Issues such as missing bolts or cross-threading can only be noticed with additional systems monitoring the assembly process.

This is where Sturtevant Richmont’s comprehensive approach to error-proofing becomes invaluable. It provides solutions to detect such errors and guides operators to resolve them.

Design, Detection and Operator Guidance: The Core of Error Proofing

Sturtevant Richmont’s error-proofing strategy begins with designing tools that minimize the chance of mistakes right from the start. A prime example is their torque wrenches with interchangeable heads, which maintain calibration accuracy even when the heads are swapped. This thoughtful design prevents errors caused by improper calibration—an issue common in many other systems. In addition, advanced technologies, like the shear beam sensor technology in tools such as the Exacta 1350 TD Series Digital Torque and Angle Screwdrivers, boost sensitivity for more precise torque application.

Equally important is error detection, which plays a critical role in Sturtevant Richmont’s approach. Tools like the Global 400 Series Torque Controller System provide immediate feedback to operators, alerting them when a mistake occurs. This prevents errors from moving down the production line and allows operators to correct the issue before any defects are created. The system uses clear visual and auditory signals, making it easy for operators to identify problems and resolve them quickly.

Operator guidance is another cornerstone of Sturtevant Richmont’s system. The tools notify operators when an issue arises and guide them on how to fix it. This feature ensures that mistakes are addressed swiftly without slowing down the assembly process. Sturtevant Richmont helps keep production running smoothly and accurately, ensuring the assembly process stays error-free by walking operators through troubleshooting steps.

“Our clients are often surprised by the significant savings realized once our control systems are integrated into their production lines,” says John Reynertson, General Manager.

Error proofing offers several tangible benefits, including improved manufacturing efficiency and significant cost savings. Immediate error detection allows production to continue at full speed without compromising accuracy. With fewer errors and the ability to address mistakes as they arise, manufacturers save on rework costs and prevent defects from progressing through production. Additionally, by preventing defects in the first place, companies can avoid costly warranty claims and ensure product quality. Many of Sturtevant Richmont’s clients experience a return on investment within the first year, thanks to the reduced downtime and increased operational efficiency these error-proofing systems provide.

A Legacy of Innovation and Quality

Sturtevant Richmont has been a leader in the torque measurement industry for over a century, with a history that reflects innovation and dedication to quality. The company’s journey began in 1924 when Walter P. Chrysler invented the deflecting beam torque wrench, a groundbreaking development that transformed torque measurement. Recognizing its potential, Chrysler granted Paul Sturtevant the license to manufacture and distribute the tool. The company’s evolution continued in 1940, with Frank Livermont founding Richmont Torque Tools, leading to a pivotal merger in 1969. The unification of Sturtevant and Richmont brought together two family-owned companies committed to quality and innovation, solidifying their leadership in the industry and creating one of the most extensive product lines in torque tools and calibration equipment.

A pivotal chapter in the company’s story unfolded in 1984 when Jack Reynertson, a retired executive, took ownership and brought in his three sons—Raymond, Donald and John— to help lead the business. Each of the brothers contributed expertise in manufacturing, sales and engineering, driving innovation and operational excellence. Their collective efforts propelled the company forward, strengthening its position as a trusted name in the industry and creating one of the most extensive product lines in torque tools and calibration equipment.

Smart Products for Modern Manufacturing

Sturtevant Richmont’s portfolio includes various tools specifically designed to meet the needs of modern manufacturing environments. The company’s hand torque wrenches, such as the 1250 Series Exacta® 2 and 1350 Series Exacta® 2, incorporate torque angle detection and wireless communication features. These capabilities provide real-time data collection and immediate feedback, ensuring correct torque application while preventing over-tightening, which can cause defects or damage.

Our Clients Are Often Surprised By The Significant Savings Realized Once Our Control Systems Are Integrated Into Their Production Lines

For specialized applications, tools like the HT Series Holding Wrenches are designed to excel in hydraulic assembly tasks where precision and alignment are paramount. These tools integrate holding devices with torque wrenches to maintain alignment and ensure consistent torque application. Digital torque and angle screwdrivers, such as the Exacta® 1350, offer precise control over torque and angle measurements, making them ideal for applications where both parameters are critical.

The company’s error-proofing solutions extend to transducerized power tools, which features closed-loop control systems for real-time feedback and accuracy. These tools integrate with advanced controllers like the Global 400 and Global 400MP Torque Controller Systems. These controllers manage complex workflows, coordinate multiple tools across workstations and provide real-time data storage and validation, enhancing efficiency in demanding production environments.

“Our expertise extends beyond technology to encompass manufacturing processes. We know how to design control systems that adapt to step and rework processes, ensuring our tools meet the industry’s evolving demands,” says Reynertson.

Sturtevant Richmont’s tools are built on a robust communication infrastructure to optimize operations further. Ethernet-based communication protocols ensure integration with plant control systems, while remote programming capabilities allow tools to be updated and calibrated without downtime. This connectivity enables real-time monitoring, simplifies tracking and reporting of torque applications and enhances operational efficiency across large-scale manufacturing processes.

Impact across Industries

The impact of Sturtevant Richmont’s tools can be seen through its clients’ success stories. An aerospace manufacturer struggled to assemble intricate aircraft wings, in one notable example. Traditional tools were cumbersome and ineffective for such tight spaces. However, by integrating Sturtevant Richmont’s Exacta 1350 miniaturized digital torque wrench, the company could streamline the assembly process and meet stringent specifications without compromising precision. The tool’s wireless functionality allowed for easy use in confined spaces, making it a game-changer for the manufacturer.

Another automotive manufacturer client faced significant challenges with leak issues during assembly. The company’s defect rates were as high as 30-40 percent. After implementing Sturtevant Richmont’s advanced control systems, defect rates dropped to zero, demonstrating the power of real-time error detection and correction. Similarly, an electrical assembly manufacturer saw a drastic improvement in production outcomes after adopting Sturtevant Richmont’s custom error-proofing solutions, eliminating rejection rates and enhancing overall quality.
