SWS Machines Two HYST HSM-2-HC Box Threads on a 17-4PH Hanger

In February 2026, Jiangsu Service Petroleum Technology Co., Ltd. (SWS) completed a single-piece threading order for a customer-supplied 17-4PH hanger. The job called for two HYST HSM-2-HC box threads, one at each end. The hanger arrived at SWS on February 1 and shipped on February 4 after machining.

The order specified a 5½-in. × 10.54 mm connection, 17-4PH material, and a box × box configuration. The customer supplied the hanger body and commissioned SWS to machine the connections. For buyers who already have a custom body, this is a practical way to source the remaining threading work without placing a new order for the complete component.

One hanger, two box ends

The order covered one component and two threads. That distinction matters when requesting a quote. A request for “one 5½-in. HSM-2-HC hanger” gives the supplier the component count, but it leaves the end configuration open. Marking the drawing HSM-2-HC box × box makes it clear that both ends require internal threading. If only one end needs work, identify that end and show the condition of the other on the drawing.

HSM-2-HC is listed on the machining authorization issued to SWS by Hengyang Valin Steel Tube Co., Ltd. (HYST). For a new order, SWS reviews the drawing against the applicable license scope and confirms the work it can accept before quoting.

If you have a hanger or another oilfield tool body that needs HSM-2-HC threading, send SWS the latest drawing, material grade, connection size, quantity, and required ship date. Mark each end as pin or box, indicate which ends still need machining, and tell us when the body will be ready. If your project calls for specific inspection or shipment documents, include those requirements with the inquiry. SWS can review single-piece and small-batch orders based on the part and the work required.
