Screw Gauge Calculator – Precision Measurement & Conversion
Find screw diameter, pitch, and convert between gauge, mm, inch, and threads instantly
What Is a Screw Gauge Calculator?
The Screw Gauge Calculator is a smart tool designed for mechanical engineers, makers, and businesses. It instantly converts screw “gauge” size (e.g. M6 or 8-32 UNC) to diameter (mm/inches), pitch, and threads per inch. You can also convert between metric and imperial, and see recommended drill/bore size for tapping.
How to Use This Calculator
- Select Metric (M) or Imperial (UNC/UNF/British).
- Enter gauge number, or select size from the dropdown.
- View corresponding diameter, pitch, TPI, and suggested drill size below.
Why Use This Tool?
- Fast, zero-error conversions for makers, hardware startups, and field engineers.
- Covers all common bolt/screw sizes and thread forms (add more to dropdown as needed).
- Ideal for manufacturing, fabrication, and quality control professionals.
FAQs
- Is this data standardized?
- Yes—based on ISO metric and Unified National (ANSI/ASME/ISO) screw standards.
