Anchor Bolt Layout

Instantly calculate count ↔ pitch, edge offsets, and coordinate positions for symmetric or flush layouts.

Layout support only. Strength, pullout, and embedment checks are not included.

Inputs

Mode
Quick actions

Align offsets to the larger one and switch the layout rule to centered symmetry.

Rounding rule
Floor: Keeps pitch conservative (n = floor(Le/pitch) + 1)
Ceil: Keep max pitch (n = ceil(Le/pitch) + 1)
Round: Closest to target pitch (n = round(Le/pitch) + 1)
Layout rule
Equal: Recompute actual pitch to fit the effective length and align to offsets
Centered: Keep input pitch and split remainder on both sides
Flush: Keep input pitch and push remainder to one side

This tool is for layout assistance only. Strength, pullout, embedment length, and concrete design are not covered.

Final decisions must follow design standards, construction procedures, and supervisor instructions.
