**Spacing of Bolts / Nails / Screws**

Spacing Formula
$s = \dfrac{RI}{VQ}$ or $s = \dfrac{R}{q}$ |
Shear Flow Formula
$q = \dfrac{VQ}{I}$ |

Where

*s* = spacing of bolts

*R* = shear capacity of bolts

*I* = moment of inertia of the section about the neutral axis

*V* = maximum shear

*Q* = moment of area
