Margate looked to force their way back into the game immediately as Pape Gueye raced down the left hand side before seeing his shot on the angle trickle wide of the far post as it looked like the Gate would be level almost straight away.
The visitors couldn’t keep up the pressure though and fell further behind on 14 minutes as Sheringham controlled the ball well before spinning in the box and rifling a low shot past on-loan goalkeeper Jon Miles who was making his Blues debut.
Margate almost fell 3-0 down on 32 minutes as veteran Midfielder Matt Spring stroked a beautiful effort just inches wide from 20 yards as Hemel really looked to bounce back from their 6-0 hammering at Bath City the week before.
Slightly against the run of play Margate were back in the game on 36 minutes as Jack Evans on his debut delivered a delightful ball into the box which was met by Tarik Moore-Azille to head home his first goal for the Blues.
Margate should have been level in the 45th minute as Michael Thalassitis raced through after a fine ball from Marvin Hamilton, however Jamie Butler in the Hemel goal just done enough to distract the striker as he forced the ball inches wide.
The second half started very even with both sides looking to avoid conceding again however it was the hosts that should have been further ahead in the 60th minute as Robinson was denied by a superb save from Miles as he looked to likely to tap home a third Hemel goal.
Hemel did extend their advantage in the 62nd minute as Sheringham was slipped through and despite it looking like Miles was winning the foot race somehow the ball slipped through the keeper’s hands allowing the former Ebbsfleet Striker to add to his tally for the afternoon and put Hemel 3-1 up.
Margate knew with just over 25 minutes left they had to throw everything at Hemel to rescue something and they were rewarded in the 73rd minute as Matthias Fanimo superbly connected with Thalassitis flick on to guide the ball home.
The visitors should have been level moments later as Jerson Dos Santos raced through on goal but despite several opportunities to pull the trigger, delayed until a Hemel defender managed to get back and cover and the chance was gone.
The final chance of the game fell to Margate as well with eight minutes to go as Marvin Hamilton swung a deep cross into the box which evaded everyone before being hacked off the line at the last second.
Defeat for Margate leaves them 13 points from safety with eight games to go and next up they travel to Kent rivals Dartford on Tuesday night who are looking to cement their place in the National League South play-offs.
