How to Use This Calculator

Enter the design tension load in pounds that the anchor bolt must resist.
Enter the concrete compressive strength f'c in psi (4,500 psi is a common structural mix).
Enter the bolt diameter in inches — common anchor bolts are 1/2" (0.5"), 5/8" (0.625"), and 3/4" (0.75").
Read the illustrative embedment depth in inches and the torque hint in ft-lb as a starting reference.
Always verify final embedment depths against ICC-ES evaluation reports for the specific anchor product.

How the result changes with Tension (lb)

Tension (lb): Design tension load the anchor bolt must resist, in pounds.
f'c (psi): Specified compressive strength of the concrete in psi. 4000-4500 is common for structural applications.
Bolt Ø (in): Anchor bolt diameter in inches. Common sizes: 1/2 (0.5), 5/8 (0.625), 3/4 (0.75).
