My tags are follows:
\documentclass{book}
\usepackage{amsmath,amssymb}
\begin{document}
$\boldsymbol{\subsetneq}$
\end{document}
I got the symbol in roman only but I need in bold face, any suggestions...
works with package bm
\documentclass{book}
\usepackage{amsmath,amssymb,bm}
\begin{document}
$\bm{\subsetneq}$ $\subsetneq$
\end{document}
Using a proper mathfont also helps:
\documentclass{book}
\usepackage{amsmath,amssymb}
\usepackage{kpfonts}
\begin{document}
$\boldsymbol{\subsetneq}$ $\subsetneq$
\end{document}

It should be remarked, however, that the first alternative uses “poor man’s bold”. With
\usepackage{kpfonts}, the\bmcommand could also be used instead of\boldsymbol, producing “real” bold in the output, provided that thebmpackage is loded afterkpfonts. – GuM Sep 6 '18 at 22:45
If you use unicode-math, there are three OpenType math fonts (as of 2019) that come in bold: Khaled Hosny’s free fonts XITS Math and Libertinus Math, and the commercial Minion Math.
The package will automatically load the bold weight as version=bold, but you can load any arbitrary OpenType or TrueType font with a command such as \setmathfont[version=bold]{XITS Math Bold}.
If you also load amsmath, \boldsymbol{\subsetneq} will still work. The unicode-math package by itself still supports the legacy commands {\boldmath ...} and {\mathversion{bold} ...}.
As alternative you could use or amsbsy package putting the command \pmb.
See the image and MWE in attachment.
\documentclass{book}
\usepackage{amsmath,amssymb,amsbsy}
\begin{document}
$\pmb{\subsetneq}$
\end{document}

Your suggestion works, but it seems to be overwriting of the same character... – MadyYuvi Apr 1 '19 at 4:58

@MadyYuvi Yes of course. Here can you see (for example) as works the command
\pmbat this link: tutorialspoint.com/tex_commands/pmb.htm – Sebastiano Apr 1 '19 at 11:23
