Product Overview
This Threaded Lock Ring is precision machined from SUS303 stainless steel and designed for secure axial positioning and mechanical locking applications. Featuring an internal M39×1.5 metric thread and a compact 6mm thickness, the ring provides stable fastening performance in rotating assemblies and industrial equipment.
The integrated mounting holes allow controlled tightening using tools or fixture pins, ensuring reliable installation and repeatable positioning.
Product Construction
The component adopts a flat ring structure with a precision-cut internal thread. The overall thickness is 6mm, offering sufficient rigidity while maintaining a compact profile.
Four evenly distributed Φ3 through-holes are machined on the face of the ring. These holes enable spanner-type tightening, fixture positioning, or anti-rotation locking during assembly.
The surface is CNC machined with smooth edges and controlled tolerances to ensure stable thread engagement and consistent fit.
