9月9日 的 Thread Pitch Gauge: Tap Drill 應用程式分析

Turn your iPhone or iPad into a calibrated thread gauge and practical machining toolkit. Thread Pitch Gauge helps machinists, CNC operators, mechanics, fabricators, and serious DIY users identify fasteners, choose drills, calculate layouts, and create shop-ready templates—right at the machine. MEASURE & IDENTIFY • Match an unknown thread with an on-screen pitch gauge. • Measure diameter with the virtual caliper. • Use the guided thread wizard and reference tables for ISO Metric, UNC, UNF, UNEF, NPT, BSPT, and SAE machine-screw standards. • Find tap drills, clearance holes, drill sizes, and metric/inch equivalents. • Create and save custom thread entries. MACHINING & LAYOUT CALCULATORS • Surface Speed / RPM / Diameter • Bolt Circle / PCD with X/Y coordinates, start angle, and CW/CCW direction • Single-row and variable-diameter hole spacing • Rectangular, circular, and oval hole patterns • Right Triangle calculations • Diameter Tape • Dividing Plate layouts SAVE, PRINT & SHARE Keep important calculations with names and notes, then export PDF reports, CSV coordinate tables, or SVG drawings. Generate true-size Diameter Tape and Dividing Plate templates where supported. BUILT FOR REAL SHOP WORK • Switch between metric and imperial units. • Works offline—no account required. • Localized for 33 languages. • Designed for iPhone and iPad. FREE TO PREVIEW Download free and preview every feature. A single Full Access purchase unlocks all calculations, interactive controls, saving, and export forever. No subscription. Whether you are identifying a mystery bolt, setting spindle RPM, laying out a flange, or preparing a drilling template, Thread Pitch Gauge replaces scattered charts and single-purpose calculators with one fast, organized shop companion. Important: Calibrate on-screen measuring tools before use. Printed template accuracy depends on printer scaling. Always verify critical dimensions and machining parameters before cutting.
