In the case of bond enthalpy, stoichiometric coefficients play a role in informing you of how many of that molecule is present. With this information, you can then count how many of each type of bond there are. In the end, the delta H of the reaction will be given by delta H (bond breakage) - delta H (bond formation).
The stoichiometric coefficients correspond to the number of bonds present and when you are using bond enthalpies to calculate enthalpy you need to know how many bonds and broken or formed. So, to calculate this you need to multiply the number of bonds present in one molecule by the stoichiometric coefficient.
