A threaded hub joins a rotating component to a shaft through internal or external threads, transferring torque securely while making installation and maintenance simpler. Triangle Machine Products specializes in precision machined threaded hubs for power transmission and industrial machinery. These are mechanical hubs for rotating assemblies, separate from the threaded conduit hubs used in electrical work.
Whether your project calls for internal or external threading, or metric or unified thread profiles, our threaded hubs perform the same on the last part of a run as on the first.
Each threaded hub we produce is machined for strength, concentricity and dependable alignment, the factors that matter most where rotational accuracy is essential. Our threaded hubs are used in heavy industrial machinery and motion control systems, where the shaft hub connection has to hold under load.
With decades of experience and advanced CNC equipment, Triangle holds tight tolerances on every hub. Compared with forming methods such as cold heading, precision machining produces cleaner thread definition and consistent parts across production runs. Learn more about our CNC turning capabilities.
No two projects are alike, so we build each custom threaded hub around your requirements. We machine male and female threaded hubs in a range of diameters, lengths and thread pitches, in both metric and unified thread profiles.
Choose coarse threads for heavy load-bearing or fine threads for precision assemblies. We produce single-piece prototypes and scale to high-volume production, and our team works closely with your engineers so each hub fits your design and performs as intended. For threaded parts that guide or support a shaft, see our threaded bushings.
Triangle Machine Products pairs machining experience with a commitment to quality and customer satisfaction. Our facility runs a full range of turning centers and multi-spindle machines, so we can set up each job for both speed and repeatability.
Our custom machining approach lets us hold tolerances and finishes that conventional hub manufacturers cannot match. Customers across industries rely on Triangle for threaded hubs designed around their application and built to perform.
Threaded hubs are mechanical components with internal or external threads that provide a secure way to fasten or couple parts. They are used in rotating assemblies such as drive shafts, gears, fans and pulleys, where threaded engagement transfers torque or retains a part. They are different from the threaded conduit hubs used in electrical installations.
Yes. We manufacture custom threaded hubs to your specifications, including thread type, dimensions, materials and tolerances, from a single prototype to a high-volume production run.
We commonly machine threaded hubs from carbon steel, stainless steel, aluminum and specialty alloys. Available finishes include black oxide, zinc plating, phosphate and custom coatings for corrosion resistance or appearance.
