Thrrread Go allows you to measure the thread pitch from a photo and combine it with the outside diameter you measured. This helps narrow down the results to likely standards, providing a practical shortlist for verification.
Can Thrrread Go identify threads from a photo alone?
No, Thrrread Go does not claim a photo alone can identify a fastener. It uses a photo for pitch measurement and requires your measured outside diameter to provide likely candidates.
What types of threads does Thrrread Go include?
Thrrread Go includes references for metric coarse and fine threads, UNC, UNF, UNEF, Whitworth W, and pipe threads like R, Rc, Rp, G, and NPT. It also covers thread-insert pilot holes.
