Many technologies, one standard: on-time quality

Our custom screw machining services are bolstered by our extensive PTJ machine library and general breadth of screw machining technology. Few can match PTJ in adherence to exacting specifications, or in the re-creation of complex geometries for high volume production of all types of specialized material parts.
