The F1554 specification was introduced in 1994 by ASTM (American Society for Testing and Materials) to cover anchor bolts and anchor rods designed to anchor structural supports to concrete foundations.
These anchors can be fabricated from headed, straight, or bent rods. Generally, the engineer on the project determines the size, shape, and grade of the anchor bolts required. Because of the custom nature of F1554 anchor bolts they are almost always either bent (L-shaped), or straight rods threaded on each end. Forged head F1554 anchor bolts are generally time and cost prohibitive for today’s construction projects.(more…)
