Widnes Vikings remain without a win in Betfred Super League this season following a 32-12 defeat to Hull FC at the KCOM Stadium.
Albert Kelly scored a brace of tries and Marc Sneyd booted all six kicks as Hull FC joined Castleford Tigers, Wigan Warriors and Leeds Rhinos on eight points.
Widnes broke the deadlock in the fourth minute when former Black and White Aaron Heremaia went through a gap to score and Lloyd White tagged on the extras.
But Hull led 14-6 at half-time as Sneyd converted tries from Kelly and Mahe Fonua and then kicked a penalty on the hooter.
And the hosts sealed the win with three tries in five minutes shortly after the restart, Danny Houghton touching down Sneyd's kick, Jamie Shaul crossing following a break from Mark Minichiello and Kelly dummying his way over.
Widnes scored again with eight minutes remaining, White converting his own try, but it was nothing more than a consolation effort.
Hull coach Lee Radford said: "First and foremost I'm pleased with the result. How we started the second half went a long way towards dictating the scoreline.
"I'm pleased with the way we went about our business. There was some fluency in what we did, which I said would come. It sets us up nicely for the fixture next week. Wigan at Wigan is a tough fixture and it's one we're looking forward to."
Widnes coach Denis Betts said. "We are making it easy for sides. We were up against a side running pretty hot with threats from all over the field but I felt we handled them well for big patches of the game.
"We went toe to toe with them in the first half, which shows we're not far off but then we hit a patch and look like a side that looks like it doesn't know what it's doing.
"I feel we've got two or three players under-performing, we're lacking that cutting edge to break open a game."
