If you’ve ever installed threaded studs into pushrods using your fingers, you know the routine: sore fingertips, uneven threading, stripped studs, and inconsistent depth. Fortunately, DU-BRO created a tool that eliminates all of this frustration—the Threaded Stud Driver. This small but powerful aluminum tool makes installing and removing threaded studs clean, accurate, and painless. Once you try it, you'll wonder how you ever built control linkages without it.
The Threaded Stud Driver is engineered for DU-BRO’s pushrod systems, especially Lazer Rods, making it a must-have tool for any serious RC airplane builder.
A Simple Tool That Saves Time and Prevents Damage
This tool may look small, but it performs a big job. Each end is pre-drilled and tapped for the most common stud sizes used in RC aircraft:
-
2-56 studs
-
4-40 studs
The exterior is fully knurled for a comfortable, non-slip grip, allowing precise control during threading. Its compact design makes it easy to keep on your bench or toss in your field box.
For additional building tools and bench accessories, DU-BRO offers a wide range of options.
How to Install a Threaded Stud with the DU-BRO Stud Driver
Installing a stud should not involve pliers, scraped fingers, or damaged threads. With this tool, the process is effortless:
1. Thread the Driver Onto the Stud
Insert the stud into the correct end—either 2-56 or 4-40—and screw it in until it stops. The tool grips the stud securely without marring the metal.
2. Install the Stud into Your Pushrod
With the stud locked into the driver, screw it directly into your Laser Rod or other DU-BRO pushrod system. The controlled grip ensures the stud threads cleanly and straight into the plastic rod.
3. Remove the Driver
Simply unscrew the tool from the stud. Your threaded insert is now perfectly installed and ready for clevis or linkage hardware.
To complete your linkage system, DU-BRO offers steel clevises, Safety Lock Kwik-Links, and ball links for all control-surface needs.
How to Remove a Threaded Stud (Without Damaging Threads)
Occasionally, you may need to back out a stud—whether you’re adjusting linkage length or re-engineering a control system. The Threaded Stud Driver makes removal clean and easy.
Here’s how:
1. Install a Matching Nut Onto the Stud
Thread a 2-56 or 4-40 nut onto the stud before attaching the stud driver. This nut creates a firm stop and prevents slippage.
2. Thread the Driver Onto the Stud
Screw on the Stud Driver until it bottoms out.
3. Snug the Nut Against the Driver
Tighten the nut so it locks the stud and driver together. Now you can extract the stud cleanly without stripping the threads.
4. Back the Stud Out of the Rod
Unscrew the stud from the pushrod using the tool. No damage, no gouging, no ruined hardware.
For replacement studs and threaded hardware, DU-BRO stocks a full range of pushrod components.
