Screw RDA Run-Down Adapters – FAQ & User Guide*

Quick Answer

Screw RDA Run-Down Adapters simulate an actual screw fastening application during torque testing. When used with compatible Mountz torque analyzers and sensors, they help create more realistic testing conditions and improve the repeatability of torque verification and calibration activities.

Who This Is For

Quality engineers
Manufacturing engineers
Process engineers
Calibration technicians
Metrology laboratories
Production teams
Companies implementing torque verification programs
Facilities performing in-house tool testing and calibration

When Should You Use This?

Use a Screw RDA Run-Down Adapter when:

Testing torque-controlled power tools
Verifying fastening tool performance
Performing calibration activities
Simulating a threaded screw application
Conducting quality control inspections
Establishing repeatable torque testing procedures

When Should You NOT Use This?

A Screw RDA Run-Down Adapter may not be necessary when:

Tool testing is not being performed
A simulated screw fastening application is not required
Torque verification is not part of the process
The adapter is not compatible with the torque range being tested

How Screw RDA Run-Down Adapters Work

A Screw RDA adapter is installed between the torque tool and a compatible torque sensor during testing.

The adapter uses a threaded fastener arrangement that allows the tool to run down before reaching final torque. This helps simulate the characteristics of an actual fastening application rather than applying torque directly into a rigid testing setup.

Result:

More representative torque testing
Improved repeatability
Better simulation of real-world fastening conditions
Consistent torque verification results

Understanding Screw Run-Down Adapters

What Is a Screw RDA?

A Screw RDA is a run-down adapter that uses a threaded screw mechanism to simulate the rundown characteristics of an actual fastening application.

Instead of immediately reaching peak torque, the tool drives the screw through the adapter before final torque is achieved.

Why Use a Screw RDA?

Many power tools perform differently in an actual assembly joint than they do when tested against a hard stationary surface.

A Screw RDA helps provide a more representative testing condition by allowing the tool to experience a rundown cycle similar to an actual fastening application.

What Makes the Screw RDA Different?

The Screw RDA combines the following features to support testing and calibration applications:

Threaded rundown simulation
Repeatable testing conditions
Compatibility with Mountz torque analyzers
Compatibility with Mountz torque sensors
Support for torque verification programs

Screw RDA vs. Standard Run-Down Adapters

Screw RDA

A Screw RDA uses a threaded fastener arrangement to simulate the rundown characteristics of a screw fastening application.

Common uses include:

Power tool testing
Torque verification
Calibration activities
Production testing

Standard Run-Down Adapters

Standard run-down adapters create resistance to simulate a fastening joint but may not replicate the actual screw rundown process.

The appropriate adapter depends on the fastening application being tested.

Available Models

The Screw RDA product family includes multiple configurations designed to support:

Power tool testing
Calibration applications
Torque verification programs
Quality control initiatives
Production testing requirements

Refer to the Screw RDA product page and datasheet for complete model listings, capacities, and specifications.

Setup & Adjustment

To use a Screw RDA Run-Down Adapter:

Connect the adapter to a compatible torque sensor
Verify all mechanical connections
Select the appropriate adapter configuration
Connect the torque tool
Perform testing or verification
Review results through the torque analyzer

Follow Mountz operating instructions for proper installation and use.

Can It Be Used with Power Tools?

Yes.

Screw RDA adapters are designed for power tool testing applications where a realistic rundown condition is required.

They help simulate the behavior of a threaded fastening application during testing and verification activities.
