## Description

BoltCalc is a pre-calibrated offline utility tool designed for DIY enthusiasts, makers, and mechanics to identify thread sizes, verify drill bit compatibility, and estimate hardware weight without needing an internet connection.<br><br>Key Features Built Into the App:<br><br>1. Thread Pitch Gauge<br>• Instantly match physical bolts against standard Metric (0.50mm to 2.50mm) and Imperial (10 TPI to 32 TPI) thread sizes.<br>• Calibrate your screen&#39;s pixel-to-millimeter ratio against standard credit cards or custom values ​​to ensure real-world accuracy.<br>• Displays commonly matched screw examples for each pitch.<br><br>2. Drill Bit Size Matching Table<br>• Search tap drill size reference charts for common Metric and Imperial fasteners.<br>• Displays exact tap drill dimensions alongside clearance fits (both close and loose tolerances).<br>• Copy dimensions directly to your clipboard or save references for quick offline lookup.<br><br>3. Live Unit Converter<br>• Swap measurements continuously between millimeters (mm), centimeters (cm), and decimal inches.<br>• Custom fraction composer converts decimal inputs to fractional representations down to 1/64&quot;.<br>• Quick-tap standard fraction list for rapid selections.<br><br>4. Material Weight Estimator<br>• Calculate hardware mass for plates, cylinder rods, hex bolts, and hex nuts.<br>• Computes weights based on manual dimension entries using standard material densities for Carbon Steel, Stainless Steel, Brass, Copper, Iron, and Aluminum.<br>• Displays estimates in both grams (g) and ounces (oz).<br><br>5. Project Hardware Counters<br>• Manage tallies for custom hardware categories (e.g. M6 Washers, 10-24 Screws).<br>• Keep counts on how many fasteners you need to purchase or check out.<br>• Reset or remove counters instantly.<br><br>6. Local Saved References<br>• Keep a bookmark list of frequently referenced drill bit matches, material weight estimates, and unit conversions.<br>• Completely searchable and filterable.<br><br>Privacy &amp; Offline Commitment:<br>• 100% Offline: Runs locally on your device CPU. No internet connection or cellular signal is required.<br>• Zero Data Collection: We collect no analytics, user statistics, or crash reports. Your calculations and saved references remain entirely private to your device.
