Olypsys for Screws
Photograph a screw or bolt using the Olypsys app and get the measurements of the thread, the standard size and a full set of measured dimensions.
Early access Screw measurement is our newest capability and is in alpha.
From Photo to Part Number
Identifying a loose screw means the correct thread gauge and callipers, and that doesn't work at all for certain types of fasteners. Olypsys measures the screw from a single photograph, then matches it against 646 thread standards in 23 families, from ISO metric to Whitworth to pipe threads.
One phone photo of a rusty bolt on the grid…
…identified as M6x1 × 12, with a 3D model and a to-scale drawing built from the measured profile.
Threads Matched
An M6x1, a 0BA and a 7/32 BSW are very nearly the same screw; some standards differ by details no photograph can resolve. Rather than pretending otherwise, Olypsys shows every thread the measurement is consistent with, ranked and quoted in its own family's units, so you can pick the one that's right for the application.
Close candidates are ranked with match scores, each quoted in its own family’s units.
A Model You Can Check
The 3D model displayed in app and online is not faked: it is built from the measured profile, with the thread swept as a real helix at the measured pitch and hand.
On the web, the same solid is posed back onto the photographed grid in a full 3D reconstruction of the capture: photo, camera and part, exactly where they were. Olypsys intelligently accounts for the 3D nature of the part and the position of the lens relative to the image.
The 3D model is built from the measurement itself, threads swept at true pitch and hand.
What You Get
Thread Identification
Matched against 646 thread standards in 23 families: metric coarse and fine, UNC/UNF, BSW/BSF, BA, BSP, NPT, wood and self-tapping.
Real Dimensions
Major and root diameter, pitch or TPI, overall, thread and shank lengths, head diameter and height. Each is measured from the photo rather than copied from a table.
Hex Heads
Across flats is measured on the head itself, with the nearest standard spanner size beside it.
Tapered & Pipe Threads
Taper is measured, not assumed, so a BSPT or NPT fitting is identified as a pipe thread instead of the nearest parallel size.
Drawing and 3D Model
A to-scale elevation with dimensions and an interactive 3D solid, both built from the measured profile, in the app and in the browser.
Full Traceability
Photos, measurements and identifications are saved to the Vault with operator and timestamp, ready for audit.

The measurement engine is available for integration. We can build it into your own app, ERP, or quality system.
Screw & Thread Identification FAQs
Questions on measuring thread pitch, TPI, metric vs imperial fasteners, and pipe threads.
How do I identify a screw or bolt thread size with my phone?
Lay the screw or bolt flat on an Olypsys calibration grid and take one photo in the Olypsys Measure app. The optical engine measures major and root diameter, thread pitch (mm) or threads per inch (TPI), overall and thread lengths, and head across-flats, then ranks matching sizes across 646 thread standards in 23 families.
Which thread standards does Olypsys support?
Olypsys matches against 646 standards across 23 thread families, including ISO Metric coarse and fine, Unified inch (UNC, UNF, UNEF), British Standard Whitworth and Fine (BSW, BSF), British Association (BA), parallel and tapered pipe threads (BSPP, BSPT, NPT), wood screws, and self-tapping fasteners.
How does Olypsys distinguish between close metric and imperial threads (like M6×1, 0BA, and 7/32 BSW)?
Instead of guessing a single thread and hiding alternatives, Olypsys ranks every standard consistent with the measured major diameter, root diameter, and pitch, quoting each candidate in its own native units (mm or TPI/inches) with a confidence score so you can select the thread family used on your machine.
Can it identify tapered pipe threads like NPT and BSPT?
Yes. Thread taper is measured directly from the profile rather than assumed parallel, allowing BSPT and NPT pipe fittings to be distinguished from parallel BSPP or metric threads.
