304 Stainless Steel Flanged Adjustment Screw, High-Precision Coaxial Threaded Rod, Customizable Per Drawing

Designed for panel wall-mounting or fine-tuning and locking of shaft systems, this component features a stepped shaft structure with a wide circular flange. The bottom flange provides a stable axial reference and contact area, effectively dispersing locking stress to prevent loosening. The central cylindrical neck defines the positioning depth, while the top standard external thread, paired with a hex nut, allows for precise axial adjustment and rigid fixation via rotation. It is commonly used in guiding mechanisms of automation equipment, internal supports for valve actuators, and fine-tuning applications in fixture tooling.

Manufacturing leverages the high-precision rotary machining capabilities of CNC lathes, with strict control over the perpendicularity between the flange face and the central outer circle, as well as the coaxiality of the neck step relative to the mounting surface. This prevents wobble or poor sealing surface contact after assembly. To address the high toughness of stainless steel, cutting parameters are optimized to suppress deformation and eliminate burrs. Fine chamfering, especially at the flange edges and thread roots, ensures operational safety and meets the aesthetic cleanliness requirements of clean environments. For tight clearance fits, outer diameter tolerances are strictly controlled to ensure smooth insertion and removal without looseness.

Equipped with high-precision CNC lathes, machining centers, and CMMs, we support non-standard customization based on 2D/3D drawings for materials (e.g., 304/316L stainless steel, carbon steel, aluminum alloy), thread standards, and surface treatments. Adhering to the ISO 9001 quality management system, our production process covers material traceability, go/no-go gauge inspection for key dimensions, and 100% visual inspection. We provide material certificates and test reports to ensure that batch deliveries meet the stringent standards for fit precision and consistency required by the petrochemical, medical device, and high-end equipment manufacturing industries.
