What are the thread pitch options for duplex fasteners?
- The thread pitch refers to the distance between individual threads on the fastener’s surface.
- Common thread pitch options for duplex fasteners include metric threads, which are expressed in millimeters, and imperial threads, which are expressed in threads per inch (TPI).
