MWD Threaded Pin

MWD Threaded Pin is a downhole tool part, is a functional MWD component, that functions as a bearing for axial force, a positioning element, and a sealing element.
This threaded pin is a critical mechanical connector used in MWD tools, requiring high-precision threading, excellent concentricity, and burr-free surfaces to ensure reliable performance under harsh downhole conditions.

MWD Threaded Pin is a downhole tool component, is a functional MWD component. Inside the MWD tool, this Downhole Threaded Pin precisely and reliably connect multiple functional modules, operating for extended periods under high temperature, high pressure, and strong vibration. It must simultaneously achieve: precise positioning, reliable load bearing, no loosening, no seizing, and no fatigue fracture.

Key Technical Challenges

Accurate thread angle and consistent pitch are required; roughening or chipping of threads is not permitted.
The thread start/end points must not have: steps, tool marks, or micro-chipping.
The material is hard, resulting in high thread cutting resistance, making it prone to scoring and built-up edge formation.
The thread roots must be free of burrs, the start and end points of the threads must be clean.
Requirement for high dimensional consistency across batches.
