F1554 Anchor Bolts
ASTM F1554 is a relatively new material specification that covers hooked, headed and threaded anchor rods in three strength grades: 36, 55 and 105. The grade designation corresponds to the yield strength of the round bar. It is essentially the same as the DOT specification AASHTO M-314.
F-1554 grade 55 is most commonly specified, although grades 36 and 105 are normally available, depending on rod diameter. ASTM F-1554 grade 36 can be specified to allow welded field correction should the anchor rods be placed incorrectly. ASTM F1554 grade 55 with weldability supplement S1 and the carbon equivalent formula in ASTM F1554 Section S18.104.22.168, can also be used for this situation, and therefor, can be substituted for F1554 grade 36.
ASTM F1554 grade 105 anchor rod is similar to the generic rod specification ASTM A193 grade B7.
Several other ASTM Specifications are sometimes specified for anchor rods. ASTM A36, A193, A307, A354, A449, A572, A588 and A687, although sometimes specified, may not be appropriate, or may be difficult to find.
Anchor Bolt Material Comparisons
A307 vs F1554
In the past, A307 Grade C was specified for anchor rods but it has been replaced with F1554 Grade 36.
A36 vs F1554
ASTM F1554 grade 36 is similar to the generic rod specifications ASTM A36. ASTM F1554 grade 55, when specified with the weldability supplement S1, is also an approved substitute, and usually more readily available.
A325/A490 vs F1554
ASTM A325 and A490 are for steel-to-steel structural bolting only, not steel-to-concrete anchoring. They should not be specified for anchor bolts, 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.
