BoltSpec Garage

BoltSpec Garage is a focused automotive workshop toolkit for working with torque values, fastener measurements, thread calculations, bolt patterns, and tightening sequences. Designed for mechanics, technicians, automotive enthusiasts and anyone working with mechanical fasteners, BoltSpec Garage brings practical calculation and reference tools together in a precision-inspired workspace. PRECISION TORQUE TOOLS Convert torque measurements between commonly used units including N·m, lb-ft, lb-in and kgf·m. Enter a value, select your units and view the converted measurement in a clear workshop interface. TORQUE SEQUENCE BUILDER Plan multi-bolt tightening patterns with a visual sequence builder. Choose a supported bolt arrangement, organize the tightening order and divide a target torque into multiple stages. For example, a target value can be divided into progressive stages such as 40%, 70%, and 100%, helping you organize a staged tightening procedure. THREAD CALCULATOR Work with common metric and imperial thread measurements. Calculate pitch and threads per inch, enter nominal dimensions and view thread information through an easy-to-read technical interface. FASTENER REFERENCE Learn the terminology and markings commonly associated with mechanical fasteners. Explore information about: • Metric property classes • SAE grade markings • Thread pitch • Nominal diameter • Bolt length • Thread length • Bolt heads • Washers • Common fastener terminology BOLT PATTERN WORKSPACE Use visual geometry tools to work with bolt-circle measurements and bolt arrangements. Enter measurements manually and view calculated values alongside a technical bolt-circle diagram. VISUAL MEASUREMENT GUIDE Understand where common fastener measurements are taken. Interactive illustrations identify bolt diameter, length, thread length, pitch, head dimensions and related measurements. WORKSHOP NOTES Create organized notes for jobs, components and measurements. Record details such as torque values, thread information, component references and additional notes for later use. SAVED SETS Keep frequently used calculations and configurations together. Save torque sequences, measurement setups, workshop notes and other useful information directly within the app. CALCULATION HISTORY Quickly revisit previous calculations instead of entering the same measurements again. Useful entries can be reopened or pinned for easier access. BUILT AROUND WORKSHOP TASKS BoltSpec Garage combines several focused tools in one consistent interface: • Torque unit converter • Torque sequence planner • Thread calculator • Fastener reference • Bolt-circle calculations • Fastener measurement guide • Workshop notes • Saved calculation sets • Calculation history • Metric and imperial measurements The interface uses a precision workshop design with technical diagrams, measurement dials and clear numerical readouts to make frequently used tools easy to identify. IMPORTANT SAFETY INFORMATION BoltSpec Garage is a calculation, organization, and general reference tool. It is not an official vehicle manufacturer service database. Torque specifications, tightening procedures, fastener requirements, and replacement instructions can vary between vehicles and components. Always verify safety-critical specifications using the vehicle or component manufacturer's official service information before carrying out repair or maintenance work.
