Threaded Bar Machining

Our threaded bar machining services utilize CNC lathes to produce high-precision threads with tolerance ±0.05mm. Capable of external threading (Acme, 梯形螺纹), internal threading, and custom profiles, we handle materials like 45# steel, 316L stainless steel, and 6061 aluminum. Bars can be machined to lengths up to 5 meters, with options for surface treatments (zinc plating, black oxide). Applications include fasteners, lead screws, and mechanical actuators. We provide full traceability via material reports and thread gauge inspections.
