ASTM F1554 grade 36 anchor bolts are manufactured from A36, low carbon steel. This is your standard, run-of-the-mill bolt grade covering anchor bolts in diameters ranging from 1/2″ through 4″. In August of 2007, F1554 grade 36 replaced ASTM A307 grade C which also covered mild steel anchor bolts.
F1554 grade 36 anchor bolts can be supplied plain black, mechanically galvanized, or hot-dip galvanized.
F1554 grade 36 anchor bolts are weldable. Common anchor bolt configurations include a rod that is threaded on both ends with a nut and/or anchor plate welded to the embedded end of the anchor bolt. Headed anchor bolts can also have an anchor plate welded to the head of the bolt if the head itself does not provide enough pull-out resistance.
The following supplemental requirements apply to F1554 Grade 36. Supplementary requirements shall apply only when specified in the purchase order or contract.
S2: Instead of the standard color coding of blue spray paint to indicate Grade 36, supplemental requirement S2 can be specified by the purchaser to require a permanent manufacturer’s identification on the end of the anchor bolt that projects from the concrete.
S3: Instead of the standard color coding of blue spray paint to indicate Grade 36, supplemental requirement S3 can be specified by the purchaser to have a permanent grade identification on the end of the anchor bolt that projects from the concrete.
When grade 36 is specified, a weldable grade 55 may be furnished at the supplier’s option.
