## Description

🚀 Speed up your engineering designs and machining setups! ANSI Fit &amp; Thread is an offline, precision calculator tailored for mechanical engineers, CNC operators, machinists, designers, and students.<br><br>Calculate standard tolerances, clearance/interference limits, thread geometries, and tap drill sizes instantly using imperial ANSI standards.<br><br>Key Features:<br><br>1. ANSI B4.1 Fits &amp; Tolerances Calculator<br>• Enter nominal sizes (from 0.01&quot; up to 19.69&quot;) and get exact limit values.<br>• Supports standard ANSI tolerance classes including:<br>  - Running/Sliding Fits (RC)<br>  - Locational Clearance Fits (LC)<br>  - Transitional Fits (LT)<br>  - Locational Interference Fits (LN)<br>  - Force/Shrink Fits (FN)<br>• High-fidelity engineering diagrams showing hole/shaft envelopes.<br>• Displays Max/Min clearances, interferences, and Allowance.<br><br>2. Unified Thread Pitch Calculator<br>• Look up standard ANSI/ASME thread details (UNC, UNF series).<br>• Instantly retrieves Major Diameter, TPI (Threads Per Inch), Pitch, Pitch Diameter, and Minor Diameter.<br>• Shaded 60° thread profile visual diagrams showing reference boundaries.<br><br>3. Tap Drill Size Calculator<br>• Instantly calculates the theoretical ideal tap drill size.<br>• Recommends the best standard drill bits (Fractional, Letter, Number, or Metric sizes) for target thread engagements.<br>• Displays real-time thread engagement percentage progress charts.<br>• Provides alternative drill sizes with precise decimal equivalents.<br>• Tapped hole engineering cross-hatch diagrams with clear annotations.<br><br>4. History Management &amp; Export<br>• Auto-saves recent calculation records to a rolling history list.<br>• Pin favorite measurements so they never expire.<br>• Search through history by custom names, sizes, or parameters.<br>• Export history to a standard CSV file for spreadsheets and reports.<br>• Native Android share sheet support with clean diagram images and text descriptions.<br><br>Why Choose ANSI Fit &amp; Thread?<br>• 100% Offline: No internet connection required. Perfect for workshops and factories.<br>• Privacy First: Zero accounts, zero analytics tracking on calculation details. Your data stays on your device.<br>• Single-Screen UX: Smooth tab navigation with clear, readable monospaced layouts—no nested menus or popups.<br>• Clean M3 Design: Optimized light and dark themes with Machinist Steel styling.<br><br>Disclaimer: This application is a curated lookup and formula reference tool. For safety-critical or production tolerancing designs, always cross-reference outputs with official ANSI/ASME standards.
