This MWE is close but not exact :

$\cdot$\raisebox{2pt}{\textbf{.}}$\cdot$

$\cdot$\raisebox{2pt}{\textbf{.}}$\cdot$

\documentclass{article}
\usepackage{amsmath}
\begin{document}
$\cdot\vcenter{\hbox{\textbf{.}}}\cdot$ but what is that good for, or why is it
better than \verb|\boldsymbol|: $\cdot\boldsymbol{\cdot}\cdot$
\end{document}
\cdot and also depends on what you put around it. I'm using \vcenter mainly for putting diagrams into equations. But it might work well with lists. Other options include tiny bullets.

Just a kludge but this works
\documentclass{article}
\begin{document}
\phantom{x}
\vfill
$\cdot$\raisebox{2pt}{\textbf{.}}$\cdot$
\vfill
\phantom{x}
\end{document}
To get the exact page center vice text space then you have to adjust margins and footer and header size.
$\bm{\cdot}$(with\usepackage{bm})? – egreg Feb 23 '18 at 09:32
