Flange Bolt Torque Reference

Internal lookup • CGI spiral wound gasket • ASTM A320 Grade L7 fasteners

Reference torque value

—ft-lb
Bolt diameter—
Prestress—
K-factor—

For reference only — not an approved tightening instruction

These values apply only to the flange, CGI spiral wound gasket and ASTM A320 Grade L7 fastener configurations described in the source tables. Do not use for different gasket types, bolt materials, coatings or lubrication conditions.

Verify against the current controlled procedure, manufacturer requirements and employer-approved bolting instructions before any field use. Engineering must validate this digital transcription. The tool does not determine a tightening sequence or approve an assembly for service.
