Cylindrical Machined Shaft with Threaded Shoulder Shaft and Welded Lifting Lug

Alloy steel's hardenability and tensile strength after heat treatment make it the standard choice for a threaded shoulder shaft where the shoulder-to-thread transition must resist combined torsion, bending, and axial load without fatigue failure. Hengtai turns and threads the shaft from alloy steel in Yancheng, with shoulder diameter, thread pitch, and runout held to your specification callouts; the welded lifting lug is added under a qualified weld procedure after machining. GJB9001c-2017, ISO 9001, ISO 14001, and ISO 45001 certifications at Hengtai's Jiangsu facility (close to 35,000 m²) cover machining and weld qualification records, dimensional inspection, and material traceability for military, offshore, and industrial equipment shaft applications. External cylindrical grinding is available for shafts requiring ground bearing journals. End markets span automotive, aerospace, and automation.
