Flange & bolt data for your entire crew
Give your pipefitters, mechanics, and engineers instant access to bolt sizing, torque specs, gasket dimensions, and pipe data — on any device, in the office or in the field.
Stop flipping through charts
Crews waste time with PDF charts, worn manuals, and spreadsheets for a single bolt length or torque value. When the wrong stud gets installed or a torque sequence is done out of order, it means rework and downtime.
Flange Bolt Chart replaces all of that with a single app that works on any phone or browser — online or off. Three taps to the right answer.
