The ASTM A354 specification covers the chemical and mechanical requirements of quenched and tempered alloy steel bolts, studs, and other externally threaded fasteners 4″ and under in diameter.

 

Two strength levels, grade BC and grade BD, are summarized in the chart below. This specification is unrestricted in its configuration and can be a headed bolt, bent bolt, or threaded rod. JF Engg Manufactures & Supplies these bolt fasteners.

Grades

 

BD	A354 BD should be considered for anchor bolts, threaded rods, other styles of headed bolts, and bolts larger than 1-1/2". Grade BD bolts are higher in strength than A354 grade BC and equal in strength to ASTM A490 bolts. Unlike ASTM A490 however, the A354 BD specification is unrestricted in its configuration.
BC	Less in Strength than Grade BD
