Stop guessing screws. Start knowing.
Snap a photo, get exact thread pitch, size, and specs. No calipers, no guessing, no wasted trips to the hardware store.

Mystery screws cost you time and money
You pull an unknown fastener from a machine, drive to the hardware store, hold it up to a gauge wall, and hope for the best. Wrong part? Drive back. Wrong thread pitch? Strip the hole. It adds up fast.
Round trip
A second drive to the store when the part turns out wrong
Near miss
A thread that almost fits is what strips the hole
Four checks
Diameter, pitch, head and drive all have to match
The faster way to identify any fastener
One photo replaces a drawer full of gauges. Get size, thread pitch, and full specs you can trust — on the spot.
Three steps. Zero guesswork.
Capture a photo with a ruler reference and get accurate specs in seconds — not minutes.
011. Snap a photo
Point your camera at the fastener with a ruler beside it. Good light and a straight angle give the best results.
022. AI does the rest
The app detects the fastener, reads the ruler scale, and calculates thread pitch, diameter, and type automatically.
033. Get exact specs
Review size, standard, and compatibility — then save or export a clean report for your team.
Less rework. Faster orders.
Real techs and makers who stopped guessing and started knowing.
“Cut our unknown-fastener downtime by 80%. We used to send someone to the hardware store with a baggie of mystery screws — now we snap a photo and order the right part in minutes.”

“I keep a ruler in my tool belt now. One photo, confirmed pitch, done. Saves me at least 20 minutes per service call when I hit a non-standard fastener.”

“Batch scan is the feature I didn't know I needed. I dumped a bin of mixed hardware, scanned the lot, and had a clean parts list exported in under two minutes.”
