Description
Product Overview
The Threaded Ball Knob M12 is engineered for demanding industrial environments where precision, durability, and ease of installation are paramount. Measuring 40mm in diameter, this round operation ball handle delivers a substantial grip surface that enhances operator control while maintaining a sleek, compact profile. The knob features a high‑quality thermoset resin body that resists chemicals, UV exposure, and temperature fluctuations, ensuring long‑term performance even under harsh conditions.
At the heart of the design is a copper insert that provides superior electrical conductivity and wear resistance. Copper’s natural properties reduce friction during repeated adjustments, extending the service life of both the knob and the mating components. The insert is securely encapsulated within the resin, protecting it from corrosion while allowing seamless interaction with metal shafts and levers.
The M12 female thread conforms to the widely adopted ISO metric standard, guaranteeing a precise, tight fit on compatible shafts. This thread size offers a balance between strength and ease of assembly, enabling quick installation with standard tools. The red finish not only adds visual distinction for quick identification in complex assemblies but also contributes an additional layer of protective coating that shields the surface from scratches and abrasions.
Key specifications include:
- Diameter: 40 mm
- Thread Type: M12 female
- Material: Thermoset resin body with copper insert
- Finish: Red powder‑coat for corrosion resistance

Usage
This ball knob is ideally suited for a broad range of machinery, including CNC routers, hydraulic presses, pneumatic valves, and conveyor system controls. Its robust construction makes it appropriate for both new equipment builds and retrofitting projects where existing handles have worn out or where a more ergonomic solution is desired.
In manufacturing settings, operators often need to make rapid adjustments to feed rates, pressure settings, or positioning controls. The smooth rotation provided by the copper‑lined thread reduces the effort required to turn the knob, minimizing fatigue during extended shifts. The 40 mm diameter offers a comfortable grip for users wearing gloves, a common requirement in metal‑working and food‑processing environments.
Because the knob’s thread is standardized to M12, it integrates seamlessly with a wide array of shafts and couplings without the need for custom adapters. This compatibility simplifies inventory management for maintenance teams and reduces downtime during part replacement. The red coloration aids in visual inventory checks, allowing technicians to quickly locate the correct component among a variety of colored handles.
When installed on safety‑critical equipment, the knob’s secure thread engagement prevents accidental loosening, contributing to overall system reliability. Its resistance to oil, coolant, and other industrial fluids ensures that performance remains consistent even after prolonged exposure to contaminating substances.
Why Choose Us
Choosing our Threaded Ball Knob means selecting a product backed by rigorous quality assurance processes. Each knob undergoes a multi‑stage inspection that includes dimensional verification, thread tolerance checks, and surface finish assessment. The copper insert is sourced from certified suppliers, and its placement is verified through non‑destructive testing to confirm proper encapsulation.
Our manufacturing facility employs advanced injection molding technology that delivers consistent wall thickness and eliminates internal voids, which can compromise structural integrity. The powder‑coat finish is applied in a controlled environment, ensuring uniform coverage and optimal adhesion to the resin substrate.
Beyond the physical product, we provide comprehensive technical support. Our engineering team is available to assist with installation guidance, torque specifications, and compatibility queries. Should any issue arise, our after‑sales service includes rapid replacement parts and a clear warranty policy that covers material defects for up to two years.
Environmental responsibility is also a core value. The thermoset resin used in the knob is formulated to be recyclable where local regulations permit, and the copper insert is fully recoverable. By selecting this component, you contribute to a more sustainable supply chain without sacrificing performance.

FAQ
What material is the knob made from?
The knob body is crafted from a high‑performance thermoset resin, while the internal insert is made of copper for enhanced durability and conductivity.
Can this knob be used with shafts other than M12?
The knob is specifically designed for M12 female threads. For other thread sizes, we recommend selecting a compatible model from our product line to ensure a proper fit.
Is the red finish purely cosmetic or does it serve a functional purpose?
The red powder‑coat finish provides both aesthetic distinction and an additional protective layer that resists scratches, UV exposure, and chemical corrosion.
How does the copper insert improve performance?
Copper’s low friction coefficient reduces wear during repeated adjustments, and its excellent conductivity makes the knob suitable for applications where electrical grounding or signal transmission is required.
What is the warranty coverage for this product?
We offer a two‑year warranty covering material defects and manufacturing errors. Should any issue arise within this period, contact our support team for a replacement or repair.
