Bolaige supplies ASTM A193 B7 stud bolts together with matching ASTM A194 2H heavy hex nuts — the standard pairing for petrochemical, refinery and flange connections where a high-strength, high-temperature bolted joint is required.
Both parts are produced to the same standard and shipped as a matched set, so the nut grade always matches the stud grade. Threaded rods to DIN 975 are available from the same production line.
When requesting a quotation, please confirm the stud diameter and length, the thread type (UNC / UNF / metric), the finish and the quantity.
Send your drawing, size or specification — our team replies with a quotation within 24 hours.
