The top of my Latex document currently looks like:

\documentclass[12pt, onecolumn]{revtex4}    
\usepackage{times}                              
\usepackage[a4paper, left=2.5cm, right=2.5cm,
 top=2.5cm, bottom=2.5cm]{geometry}    
\renewcommand{\baselinestretch}{1.15}
\usepackage[font=small,labelfont=bf]{caption}

\renewcommand\Dated@name{}
\makeatother

\usepackage{fancyhdr}

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

    You have many options: sectsty, titlesec, etc. – user156344 Apr 6 at 16:02

    You're presumably using the revtex4 document class for a good reason, e.g., because you're planning to submit a paper to a journal which requires authors to employ the revtex4 class. If that's the case, it's probably a poor idea to modify the appearance of subsubsection-level headers. For one, it'll immediately earn you the enmity of the journal's editorial staff, and the editors may decide to reject the paper solely based on its failure to conform to revtex4 formatting conventions. – Mico Apr 6 at 16:33
  • Off-topic: No need to load both graphics and graphicx. And, almost certainly no need to load epsfig. – Mico Apr 6 at 16:47

    @Sveinung I use the singular form of word "answer". That means I only pointed to one answer (sorry if I was not clear). And that answer can be used. We can never say this answer or that answer is the best option. It is very opinion-based. I keep my opinion: I voted for closure. – user156344 Apr 6 at 17:04

    @Sveinung Then you don't vote to close it. Nothing simpler :)) – user156344 Apr 6 at 17:09

NB! Take note of @Mico’s comment to your question before you apply this patch

In Revtex v4.2c, \subsubsection is define with the following command:

\def\subsubsection{%
      \@startsection
        {subsubsection}%
        {3}%
        {\z@}%
        {.8cm \@plus1ex \@minus .2ex}%
        {.5cm}%
        {\normalfont\small\itshape}%
    }

I tried to redefine the command:

\def\subsubsection{%
  \@startsection
    {subsubsection}%
    {3}%
    {\z@}%
    {.8cm \@plus1ex \@minus .2ex}%
    {.5cm}%
    {\normalfont\small\bfseries}%
}

This redefinition changes the font to boldface, but the alignment of the subsection was changed, too. Obviously, the alignment is applied later and is cancelled if you redefine the command by using \def.

\patchcmd worked better:

\documentclass[12pt, onecolumn]{revtex4}    
\usepackage{etoolbox} 
\makeatletter
\patchcmd{\subsubsection}{\itshape}{\bfseries}{}{}
\makeatother
\begin{document}                    
\section{test}
\subsection{Testing}
\subsubsection{More testing}
\end{document}

Just add the line:

\patchcmd{\subsubsection}{\itshape}{\bfseries}{}{}

after the other patchcmd lines in your example, and you have your bold subsubsection. .
