HDD Thread Reference
With no standardization of pipe and tooling connections in the HDD industry, it can be a challenge at times to determine the identity of a thread connection. Below are profiles and key specifications of the most commone OEM and standard threads found in the industry.
Most threads can be identified using three primary measurements and by viewing the thread form or shape of the thread.
- Pin Length: measured from the base of the thread to the tip.
- Shoulder Diameter: diameter of the base of the pin (male) or box (female).
- Threads Per Inch (TPI): Number of thread "peaks" counted in one inch.
Click on the type of thread below or scroll down to view all threads. |
