Grades

 F1554 Grade 36    Low carbon, 36 ksi yield steel anchor bolts
 F1554 Grade 55    High strength, low alloy, 55 ksi yield steel anchor bolts
 F1554 Grade 105    Alloy, heat treated, high strength 105 ksi yield steel anchor bolts

 

 ** When Grade 36 is specified, a weldable Grade 55 may be furnished at the supplier’s option.

 

Threading:  Threads shall be rolled, cut or ground at the option of the manufacturer, unless otherwise specified
