Carbon Steel Fitting with Threaded Flange Boss and Machined Mounting Holes

We supply this threaded flange boss with controlled geometry so you avoid extra rework during assembly. For your part, we hold major diameter range and surface texture requirement as defined checkpoints for repeatability. When the threaded flange boss requires a fixed tolerance window and datum scheme, provide a dimensioned drawing so boss thread, pilot diameters, and mounting hole positions are fully defined. In Huai'an, our ISO 9001 and IATF 16949 facility supports precision machining for non-standard mechanical components. The factory covers over 15,000 m². End markets span automotive, medical equipment, and automation. Pricing is based on material grade, tolerance class, and volume per release, with timing influenced by surface finish requirement and any special inspection you specify.
