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.
