F1554 anchor bolt

 ASTM A325 and A490 are for steel-to-steel structural bolting only, not steel-to-concrete anchoring, because they have special heading and threading requirements and are generally available in lengths up to 8 inches only. ASTM A449 is the strength level equivalent of A325, and ASTM A354 or ETD 150 is the strength level equivalent of ASTM A490 in a rod specification with more general heading, threading and other requirements.

Several other ASTM Specifications can also be used. For applications involving un-headed rods, ASTM A36, A193, A307, A354, A449, A572, A588 and A687 can be specified. For applications involving headed rods, ASTM A307, A354 and A449 can be specified.

 ASTM F1554 grades 36 and 105 are essentially the anchor-rod equivalents of the generic rod specifications ASTM A36 and A193 grade B7, respectively. ASTM F1554 grade 55, when specified with the weldability supplement, is similar to an ASTM A572 material that is intermediate between grades 50 and 60.

Grade 36 (essentially A36 bar) is most commonly specified, although grades 55 and 105 are normally available when higher strength is required. ASTM F1554 grade 36 can be specified to allow welded field correction should the anchor rods be placed incorrectly in the field. ASTM F1554 grade 55 with weldability supplement S1 and the carbon equivalent formula in ASTM F1554 Section S1.5.2.1, can also be used for this situation.

 ASTM F1554 is a relatively new material specification that covers hooked, headed and threaded anchor rods in three strength grades: 36, 55 and 105.
