Screw Identifier: The Fastener Mystery Solver

Field notes

The described workflow uses a ruler placed beside the fastener so the app can estimate scale before returning thread pitch, diameter, type, and standard. The page distinguishes single-photo identification from batch scanning, which groups mixed hardware and produces counts for inventory or ordering. It also links to reference material covering thread pitch, screw sizes, wood-screw gauges, metric-to-imperial conversion, and visually confusable head and drive types.
