Precision Threaded Products is a specialty manufacturer of aerospace grade studs, inserts, pins, bushings, and screws used in aircraft engine components and sub-assemblies.

Our machining facilities include seven advanced CNC turning centers, eight roll threading machines, and a variety of milling, drilling, and secondary machining equipment. To reach specified levels of quality and consistency, all of our parts are machined from fully certified bar stock. Parts are machined from a variety of aerospace steels, including high temperature stainless steel (A286). For critical or specialized applications, we also offer exotic metals like Inconel, Waspaloy, and Titanium. We have the technical knowledge and experience needed to properly machine these difficult to work with materials.

Our machining process can accommodate parts in a variety of sizes, ranging from 1/16" up to 1-1/4" in diameter and up to 10" in length. Tolerances as close as +/- .0001 on diameters and +/- .0002 on thread pitch diameters are maintained. For custom or non-standard applications, we can produce studs requiring secondary operations or in special configurations. These include shouldered studs, drilled studs, and studs with locking features or wrench pads.
