NOTE 4—Research conducted on bolts of similar material and manufacture indicates that hydrogen-stress cracking or stress cracking corrosion may occur on hot-dip galvanized Grade BD bolts. Chemical Composition 5.

The steel shall contain sufficient alloying elements to qualify it as an alloy steel. NOTE 5—Steel is considered to be alloy, by the American Iron and Steel Institute, when the maximum of the range given for the content of alloying elements exceeds one or more of the following limits: manganese, 1.

The chemical composition thus determined shall conform to the requirements given in Table 1. For sizes larger than 11? Mechanical Properties 6. Fasteners less than three diameters in length and studs less than four diameters in length shall have hardness values not less than the minimum nor more than the maximum hardness limits required in Table 2, as hardness is the only requirement.

When equipment of sufficient capacity for full-size testing is not available, or when the length of the fastener makes full-size testing impractical, machined specimens shall be tested and shall conform to the requirements in accordance with Table 4. In the event that fasteners are tested by both full-size and by the machined test specimen methods, the full-size test shall govern if a controversy between the two methods exists.

Dimensions 7. Grade Brinell Minimum? After zinc coating, the maximum limit of pitch and major diameter may exceed the Class 2A limit by the following amount: Diameter, in. Workmanship 8.
