Anchor rods also known as anchor bolts are used in construction projects to secure structures to concrete. They come in a variety of types, each suited for different applications depending on the load requirements and environmental conditions. In this blog post, we'll explore the different types of anchor rods.
One end of anchor rod is embedded into the concrete, while the opposite end is threaded to attach structural support. AISC has changed its terminology "anchor bolt" to "anchor rod" to eliminate confusion between structural bolting applications.

ASTM F1554 specification was introduced in 1994 and covers anchor bolts designed to anchor structural supports to concrete foundations. F1554 anchor bolts can take the form of either headed bolts, straight rods, or bent anchor bolts. The three grades 36, 55, and 105 designate the minimum yield strength (ksi) of the anchor bolt.
The bolts can be either cut or roll threaded and a weldable grade 55 can be substituted for grade 36 at the supplier’s option. Color coding on the end – 36 blue, 55 yellow, and 105 red – helps facilitate easy identification in the field.
