Amakhosi have farmed out the 18-year-old to gain game-time in Durban.
"We have Sakhile on loan to us from Chiefs and he is doing fine,” says Thanda team manger Thabani Gumede.
"He hasn’t played much so far because he wasn’t with us through our pre-season and only joined just before the start of the season.
"What we don’t have any doubts about is that he will definitely add value to our team because he is forever improving and is a quality young striker.
"All he needs to do is fight for his place and start playing regularly."
Hlongwa joined Chiefs from eThekwini Coastal Academy.
