## Description

Flange Bolt Chart is a fast, offline tool for pipefitters and engineers to look up flange dimensions, bolt patterns, torque data, and gasket specs in seconds. All data is stored locally, so lookups are instant without internet access. Access is three taps: flange data, bolt data, and pipe/gasket details.

The app covers flange dimensions, bolt sizes, bolt circle data, torque sequences and target torque, gasket data, and ASME B16.5 references. It supports a wide range of sizes and classes, with values calculated or sourced from official standards. Designed to be faster and less error-prone than PDF charts, Flange Bolt Chart helps professionals work efficiently and accurately.
