A354 BD/Grade 8 All Thread Rod

ASTM A354 Grade BD all thread rod is equivalent in strength to SAE J429 Grade 8. It is manufactured from alloy steel, quenched and tempered. Dimensional specifications are governed by ASME B18.31.3. ASTM A354 specifications covers fasteners for applications at normal temperatures, where high strength is required. Also for limited application at elevated temperatures.

 

Governing StandardsGrade BD

ASTM A354 Covers the chemical and mechanical requirements of quenched and tempered alloy steel bolts, studs,and other externally threaded fasteners 4 in. and under in diameter for application at normal atmospheric temperatures, where high strength is required and for limited application at elevated temperature.
ASME B18.31.3 Covers the general and dimensional data for inch series threaded rods.
ASME B1.1 UNC & UNF Class 2A Specifies the thread form, series, class, allowance, tolerance, and designation for unified screw threads.
