Bruce's side entertain Newcastle on Saturday and they go into the game 11th in the table, six points clear of the relegation places.
"I said seven months ago we need 10 wins and if you get the 10, that is always enough, for me, to keep you safe," said the Tigers boss.
"That was always the aim. We have won eight and it's been difficult getting the eight.
"We have come to March, we have 10 or 11 games to go, and our aim now is to sustain it and stay there.
"At the moment, we are probably second-top of our division (places 10-20).. West Ham are above us and there are 11 teams. Can we stay there? That has got to be the aim.
"We have to try and see it through if we possibly can."
Hull have picked up five of their wins at the KC Stadium this season and Bruce believes that has been crucial in keeping them away from the drop-zone.
"Away from home, we had the top eight in our first eight or nine games away from home," added Bruce.
"So our home form was going to be crucial, which every club needs if they are going to avoid relegation.
"If you can then win a few games away from home against teams in and around you, and we have managed to do that in the last couple of games, that gives you breathing space.
"We have gone to Sunderland and won and we went to Cardiff last week (and won again).
"I hope that continues because we have two or three teams around us away from home and if we can sustain our home, we could have a very good end to the season.
"That will be the aim if we can."
Hull strengthened their attack in January with the signing of strike-duo Nikica Jelavic and Shane Long from Everton and West Brom respectively.
The two have shared five goals in the five games they have started so far and Bruce feels they have made his side a "different animal".
"I'd love to say it's all in the training but they're two very good players playing together," added Bruce.
"There's a lot said about coaching but a good player is a good player and in management the more of them you've got the easier it becomes.
"They came in at just the right time and all of a sudden we're a different animal up front.
"That's no disrespect to what we had before but at the end of the day they're two £6m players and you'd expect that. We're delighted we've got them and I think they're a terrific partnership.
"That's what you invest in, they give you that little something you'd didn't have before."
