Product catalog summary

Introduction
The document focuses on the accuracy, durability, and reliability of Sturtevant Richmont torque screwdrivers, highlighting their critical role in military equipment assembly where consistency and quality are paramount.

Calibration and Testing Challenges
It addresses issues encountered by a calibration lab manager who found discrepancies between lab testing and actual application of torque screwdrivers. The problem was linked to both the torque tester and the screwdrivers, except for those from Sturtevant Richmont, which surpassed the ASME B107.14M accuracy requirement of +/- 6%.

Customer Feedback and Product Development
Sturtevant Richmont values customer feedback, which has been crucial in enhancing their torque screwdrivers over 70 years. The document discusses the challenges of ensuring repeatability and accuracy, noting the impact of downforce during assembly.

Testing Procedures
A three-step testing process for torque screwdrivers is outlined, including tests with and without downforce. Results showed significant torque value variations when downforce was applied, underscoring the importance of considering this factor in testing.

Thrust Load Testing Results
Test results for PM Series screwdrivers under different thrust loads are detailed, showing accuracy variations. The PM-5, PM-15, and PM-36 models were tested, indicating that downforce affects torque output.

Product Features and Specifications
Features of various torque screwdriver models are listed, including durability, anti-backlash design, and automatic clutch release to prevent over-torquing. Specifications for different models, such as range, length, weight, and drive type, are provided.

Conclusion

The Curious Cal Lab Manager I was calibrating tools for more than 11 years before I became the lab manager. We make equipment for the military. Consistency and quality are important because lives are at stake. We were experiencing significant quality issues on the equipment made with torque screwdrivers. I knew I was following the ISO 6789 to the letter, but quality was not where it was supposed to be. I went out on the floor to watch the team assembling equipment. The first thing I noticed is that there is a discrepancy between the way a torque screwdriver is tested in the lab and how it is...

Challenges And The Torque Screwdriver When our customers talk, we listen. Very carefully. In fact all through those 70+ years that we’ve been in business, we’ve listened to our customers. We listen because what they say is valuable and important. Digilock Control Mechanism revolutionizes manual torque adjustment. When customers talked about our torque screwdrivers they taught us a thing or two. The customers provided an interesting way to answer the question "Is there a screwdriver more accurate and reliable than this one?" Assembly Versus the Lab Torque screwdrivers are all about repeatability...

Far more than anyone would calculate. To better understand the differences we put our screwdrivers on the tester. Our testers are designed to include down force as part of the equation. We created a three-step process: • Test the screwdriver ten (14) times using the ISO 6789 prescribed process and record results. Note: The ISO 6789 standard does not recognize any down force as part of the test process. • Test the same screwdriver again...
