## Description

Flange Bolt Size & Torque makes it easy to look up flange, pipe, and bolt data offline in seconds. All information is stored locally for instant lookups and offline operation, with ASME B16.5 based values for flange bolts, sizes, and torque patterns.

Includes bolt counts, diameters, torque sequences images, gasket and pipe data, and more across NPS ranges. Designed for pipefitters and steamfitters, the app speeds up work and reduces errors, with support for official standards and offline access.

## Review summary

Users praise the app for being easy to use and fast, with broad torque data and patterns that help in planning and fieldwork. It’s a time-saver and generally reliable. However, repeated concerns include the move to subscription pricing with limited free access, stability issues after updates, incomplete coverage for certain flange types, and occasional data inaccuracies in torque recommendations. Despite these drawbacks, many users still find it valuable, and report responsive support when issues arise.

### Pros

- Easy to use with a clean interface
- Fast access to a broad set of flange data and torque information; a real time-saver
- Torque patterns included and helpful for selecting wrench sizes
- Useful in both field and office; reduces need for laminated charts
- Generally reliable data and responsive support from the developer

### Cons

- Subscription pricing / paywalls with ongoing costs
- Stability issues after updates (crashes, black screens, not opening)
- Incomplete coverage for some flange types (e.g., Code 61/62)
- Some torque data/patterns are inconsistent or inaccurate
- Some features require unlocking or upgrading to access torque values
