Precision anodized metal ball head tie for servo linkages. Ideal for heavy-duty steering in RC boats, planes, and robotics.
Plastic linkages often flex or snap when pushed to the limit in high-speed RC boats or heavy-duty robotics. The Metal Ball Head Positioning Tie (Red Model) is the mechanical upgrade that solves this connection weak point. Designed for builders who demand rigidity and precision, this anodized aluminum component replaces fragile stock parts with a professional-grade linkage solution.
Built for Durability and Aesthetics While generic linkage ends are often cast from soft alloys with loose tolerances, this unit is machined for consistent fitment. The anodized red finish provides not just a striking aesthetic for custom builds but also essential corrosion resistance—crucial for RC boat applications where water exposure is constant. The steel swivel ball ensures smooth articulation, allowing your servo's torque to be transferred directly to the control surface without the "play" found in budget parts.
The Probots™ ProSpec Grade Difference We understand that a single failed linkage can crash a drone or sink a boat. That’s why we explicitly verify that the ball movement is smooth yet tight, ensuring zero backlash. Unlike bulk-bin parts that may arrive with burrs or seized joints, our Probots™ QC-Pass process ensures every unit is inspected for thread quality and free movement before it leaves our facility. This is a component you can trust for high-stress maneuvers.
Versatile Application Range Whether you are building a high-speed brushless marine vessel, a 1/10 scale crawler, or a custom robotic arm, this tie rod end provides the robust interface you need. It accepts standard M3 threaded rods, making it a universal fix for varied projects. Upgrade your build’s reliability today and experience the difference that rigid, metal-to-metal control brings to your piloting.
Note: Please verify the thread pitch and dimensions (M3 male stud and M2 female socket) before purchase. Improper sizing can lead to thread stripping or mechanical failure during operation.

Key Applications & Projects:
Project Evolution:
Past Projects (Prerequisites): If you have mastered basic servo control using the white nylon horns and bent wire linkages included with standard servos...
Feature Upgrade: This component unlocks Heavy-Duty Vectoring. By replacing wire bends with a ball-head interface, you eliminate "play" (slop) in the system. This allows for precise, jitter-free control surfaces.
Effort Level: Intermediate. Requires measuring and cutting threaded rods to length.
Virtual Technician & Wiring Guide:
⚠️ Compatibility Warning: Please measure your linkage rods before purchasing. This unit typically accepts M2 threaded rods.
Package Includes:
1 X Metal Ball Head Linkage Tie Rod End M3/M2 for RC Servo & Boat (Red)
Frequently Asked Questions (FAQ)
What is the thread size for the connecting rod?
It typically accepts standard M2 threaded rods.
Does this come with the mounting screw and nut?
No, this listing is for the Ball Head Tie unit itself.
Is this suitable for saltwater RC boats?
Yes, the anodized finish resists corrosion; rinse with fresh water after use.
Can I use this with an MG996R Servo?
Yes, MG996R servos are powerful enough to utilize this linkage effectively.
What is the "Red Model" difference?
The "Red Model" refers to the anodized color finish.
How much weight does it add compared to plastic?
It adds approximately 2-5 grams per unit.
Is the ball captive or removable?
The swivel ball is captive and cannot be removed.
Will this fit a 1/18 scale RC car?
It is likely too bulky; best suited for 1/10 scale and larger.
Do I need threadlocker?
Yes, we recommend Blue Loctite on the threads to prevent loosening.
What tools do I need?
Small pliers/wrench and a hex driver.
Can this be used for a steering drag link?
Yes, it is excellent for drag links.
Is the movement stiff?
Probots™ QC-Pass ensures smooth movement; silicone oil can help break it in.
Can I drill the hole larger?
No, the ball is hardened steel and difficult to drill.
Works with push-pull configurations?
Yes, ideal for push-pull setups.
Max articulation angle?
Approx 25-30 degrees in any direction.
Is it magnetic?
The internal ball is magnetic, the body is not.
Good for 3D printer delta arms?
Yes, if dimensions match your effector.
M2 vs M3 difference?
Measure your rod diameter: 3mm is M3.
Will it rust outdoors?
The body won't, but keep the steel ball oiled.
Stronger than white plastic?
Significantly stronger and more rigid.
