Who decides tap vs thread-mill vs insert?

Tap, thread-mill, or a helical insert (if agreed) is a process choice. Call out size, hand, depth, and whether the thread is critical. Aluminum and 304/316 do not tap the same; we assess per part.

Quantity 1 can include a thread method review. 12h target UTC+8. Fine pitch and deep blinds are not a default “will tap.”

Mask threads before anodize if they must stay to size. Finish days sit on production. We do not cut implant bone screws. Tick inspection if needed.
