SSML Premier Division leaders Kings started the game brightly and Alex Campana floated in a pin-point cross from the left for Hutchins to execute a glancing header past Ross Hampton.
Campana, clearly relishing his role on the left of a front three, cut inside with a jinking run five minutes later and Hampton could only tip his fierce shot onto the crossbar for Jackson to net the rebound from close range.
Sun had a moment when the assistant’s flag stayed down and Carl Penny was through on goal, but Ant Ladyman made a superb block and Kings killed the contest with two goals in three minutes before the break.
Mitchell Weiss challenged the shared possession of keeper and defender, the ball ran free, and Hutchins lobbed the back-pedalling Hampton from a position almost on the touchline.
Hutchins then picked out Jackson and the skipper controlled the ball, twisted past a defender and unleashed an unstoppable shot into the net for 4-0.
Any thoughts of a quieter second half were dispelled as Kings added two more in the first 10 minutes.
A perfect diagonal cross-field ball from Weiss found Hutchins – who was similarly enjoying his wide right role – and he took it in his stride to complete his hat-trick.
Not to be outdone, Jackson rose to head home a Connor Toomey cross as everything Kings did turned to goals.
Home skipper Ashley Lewis was dismissed for a second yellow and, as frustrations boiled over, a trespass in the away technical area by a member of the home bench resulted in a scuffle and three dismissals from the dugouts.
It failed to take the shine off of an exuberant Langley performance, though – completed when a Campana corner was only parried by the keeper and Joe Debayo marked his debut with the seventh goal.
