The first clear-cut chance for the Bees came in the 36th minute when Shane Cojocarel saw his effort cleared off of the line.
After the break, Andre Blackman forced a good save out of Tom Lovelock in the Hendon goal. From the corner, captain Joe Payne had an effort blocked on the line, it fell to Darnell Smith whose effort was deflected up, Tin Plavotic headed towards goal but again it was denied by the Hendon 'keeper.
Soon after this, it was 2-0 when Harold Joseph poked home from a corner kick.
After the hour-mark, Fumnaya Shomotun flashed a shot across the face of goal.
Coulthirst was also brought down by Lovelock but referee Daniel Simpson waved play on.
In the dying moments, Ephron Mason-Clark had two efforts remarkably cleared off the line as Hendon defended like their lives depended on it.
