ASTM A193 — Scope
The table below lists the dimensions catalogued for inch fully threaded rod, astm a193 b7 under ASTM A193. The scope of ASTM A193 itself is not summarised here — where a figure matters, confirm it against the published document.
Tolerance & Product Grades
Product grade is a concept from dimensional fastener standards and does not apply to ASTM A193. Tolerances for this part are the limits shown against each dimension in the table.
Dimensions Specified by ASTM A193
| Nominal size | Thread series | Standard lengths (ft) | Minimum tensile (ksi) | Minimum yield (ksi) | Elongation minimum (%) | Finish options | Reference standard |

Equivalent Standards
Where direct equivalents exist (ISO ↔ DIN, ISO ↔ ASME), they are listed on the parent Inch Fully Threaded Rod, ASTM A193 B7 page.
Always confirm against the dimensions on this page, since some "equivalent" standards differ in tolerances and head geometry.
Companion Standards
A complete specification for inch fully threaded rod, astm a193 b7 normally cites several documents: one for the geometry, one for the material or mechanical properties, and one for the finish. ASTM A193 is one of them, not all of them.
Custom manufacturing · Made to drawing
Need a bolt to this standard in a non-standard size?
Parts built to ASTM A193 are already in the catalog, so a special is usually a variation on existing tooling rather than a new design — which is what keeps the cost down. Made by cold heading or hot forging.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.
