OEM Ball Head M2, Bore 2.1 mm – Precision RC Steering Component
The OEM ball head M2 with a 2.1 mm bore is a compact steering component designed for RC models and precision mechanical assemblies. It enables smooth, low-friction pivoting in control linkages and steering mechanisms.
2-piece set provides a complete pair for symmetric steering link installation
M2 thread and 2.1 mm bore fit standard RC servo arms and control horns
Low weight of 11 g per pair keeps the overall mass of the steering assembly minimal
OEM-specification build ensures consistent tolerances and reliable fitment
What sets the OEM Ball Head M2 apart
Unlike generic ball heads, this component is manufactured to OEM specifications with a precise 2.1 mm bore and M2 thread, ensuring a secure, backlash-free connection in RC steering linkages. The 2-piece set covers both sides of a symmetric linkage without the need for separate sourcing.
Ideal for...
RC model builders and hobbyists working with servo-driven steering systems, particularly in on-road and off-road vehicles where precise Ackermann geometry and minimal play at the pivot point are essential. Also suited for mechanical assemblies requiring a compact, low-profile ball joint.
Application of the OEM Ball Head M2
Mount the ball head onto the servo arm or control horn using the M2 thread, then secure the opposing link through the 2.1 mm bore. The 2-piece set allows parallel installation on both sides of a steering linkage. Typical use cases include RC car steering arms, robotic joint assemblies, and precision mechanical linkages in model engineering.
OEM is a generic manufacturer designation used across the RC and model-building sector for components that meet original equipment specifications without carrying a dedicated brand name. Products under this label are typically sourced as replacement or upgrade parts for established RC platforms.
It serves as a precision pivot joint in RC steering linkages and mechanical assemblies, connecting servo arms or control horns to link rods via the M2 thread and 2.1 mm bore.
Two identical ball head units, enabling symmetric installation on both sides of a steering linkage or parallel mounting at two pivot points in a single assembly.
Thread: M2. Bore diameter: 2.1 mm. Weight: 11 g for the pair. Material: OEM-specification metal alloy (exact composition not specified by the manufacturer).
Screw the M2 thread into the servo arm or control horn, then insert the link rod through the 2.1 mm bore. No additional fasteners are required for the basic mounting.
Yes. The M2 thread and 2.1 mm bore are standard dimensions widely used across RC servo arms, control horns, and steering linkages in the RC model-building sector.
