The V one app is a standalone fastener reference guide and a handy tool for your home workshop. It puts everything you need to work with bolts, screws, nuts, and other hardware into a single app.
The app helps you identify unfamiliar fasteners based on their physical characteristics. A step-by-step visual identification tool guides you through narrowing down details like head shape, drive type, profile, and other distinguishing features, then displays the best matches from the catalog. It also helps you organize your own fastener inventory: create virtual bins, add parts, and record dimensions, quantities, and personal notes.
The app requires no registration, contains no ads, and does not share data with third parties. The catalog, favorites, history, and user records are stored locally on your device.
Identify any part, decode markings, and get organized with the V one app.
