Precision CNC Machined Stepped Dual Thread Adjustment Shaft Custom Stainless Steel Positioning Screw
Description
This Precision CNC Machined Stepped Dual Thread Adjustment Shaft is a high-accuracy custom component designed for mechanical positioning, fine adjustment, and locking applications in demanding industrial environments. Manufactured through advanced CNC turning and threading processes, the part features a multi-step shaft structure combined with dual external threads, enabling both coarse adjustment and precise fine-tuning within a single integrated design.
The upper fine thread section allows for accurate micro-adjustment, while the larger diameter threaded section provides strong fastening and load-bearing capability. The bottom step or flange ensures reliable axial positioning and structural stability during operation. This functional combination makes it an ideal solution for applications requiring repeatable positioning and precise mechanical control.
Produced from high-quality materials such as stainless steel, alloy steel, or titanium, the component offers excellent strength, corrosion resistance, and durability. Surface treatments like passivation, black oxide, or polishing can be applied to meet specific environmental and performance requirements.
Widely used in industrial machinery, automation equipment, tooling fixtures, and precision instruments, this part is typically customized based on customer drawings or functional requirements. Tight tolerances and strict quality inspection processes, including thread gauges and CMM measurement, ensure consistent performance and high reliability.
We support full OEM/ODM services, from prototype development to mass production, providing flexible solutions tailored to your application.
