Análisis de la app Thread Pitch Gauge - Tap Drill para 3 de mayo

Turn your iPhone into a precision thread pitch gauge, virtual caliper, and complete fastener reference — all in one app built for machinists, mechanics, engineers, and DIYers. MEASURE THREAD PITCH Place any bolt, screw, or fastener directly on your screen and align it with the on-screen guide lines. Adjust pitch with fine-grained controls (down to 0.001 mm), pinch to zoom, rotate for angled threads, and lock the gauge when you find a match. The app instantly shows matching thread standards with confidence ratings. VIRTUAL CALIPER Drag the on-screen jaws to measure outer diameters with real-time readout in millimeters or inches. The app suggests the nearest standard thread diameters so you can quickly identify unknown fasteners. IDENTIFY ANY THREAD STANDARD A built-in database covers the most widely used thread families: • ISO Metric (M series — coarse & fine) • Unified National Coarse (UNC) • Unified National Fine (UNF) & Extra Fine (UNEF) • National Pipe Taper (NPT) • British Standard Pipe Taper (BSPT) • SAE Machine Screw Search, filter, and browse detailed specifications including pitch, TPI, major diameter, tap drill sizes, and clearance hole dimensions for every entry. TAP DRILL & CLEARANCE HOLE CALCULATORS Select any thread from the database and instantly get: • Recommended tap drill in mm, decimal inch, and fractional inch • Nearest standard metric and inch drill sizes • Clearance hole diameters for close, normal, and loose fits THREAD CONVERTER Convert freely between pitch (mm), threads per inch (TPI), decimal inches, and millimeters. See the nearest standard threads for any value you enter. DRILL SIZE REFERENCE Complete reference tables for metric, number (#1–#80), letter (A–Z), and fractional (1/64" – 1") drill sizes with instant mm ↔ inch conversion. GUIDED THREAD WIZARD Not sure where to start? The step-by-step wizard walks you through: 1. Thread type (screw/bolt or pipe fitting) 2. Unit preference (metric or imperial) 3. Approximate diameter 4. Estimated pitch …and returns ranked candidates with confidence levels. SCREEN CALIBRATION Accurate on-screen measurement requires calibration. Choose from three methods: • Auto Device Preset — instant setup using known screen specs • Credit Card — align a standard card for quick calibration • Manual Ruler — the most precise method for demanding work BUILT FOR THE WORKSHOP • High-contrast dark and light gauge backgrounds • Large, readable monospaced values • Haptic feedback on snap-to-standard and selections • Works 100% offline — no internet required • Save measurements with notes, tags, and wear condition • Favorites and search across all saved data • Metric ↔ Imperial toggle everywhere • Custom thread profiles for non-standard or antique fasteners Whether you are identifying a mystery bolt in the field, looking up a tap drill at the bench, or checking clearance hole specs on a job site — Thread Pitch Gauge Pro gives you every answer in seconds, right from your pocket.
