Goals from Evan Garnett and Jonathan Williams ended the Green Backs unbeaten run with strong performances all across the field.
Garnett opened the scoring for the Nailers as he danced past two Bedworth defenders before slotting his effort low into the bottom right.
This came after the forward had a goal wrongly ruled out by the referee.
Garnett cut in onto his right before firing an effort towards goal.The shot hit the right post before hitting the side netting on the other side of the goal and bouncing out.
But the officials somehow missed that the ball had crossed the line and play continued; much to the bewilderment of Garnett and his Belper team mates.
Williams doubled the lead for the Nailers from the spot after Ruben Wiggins-Thomas was brought down in the box.
The midfielder slotted the penalty home well to give the Nailers a little extra breathing space.
It looked as if Belper had made it 3-0 with only minutes to go.
Steadman countered with pace into the Bedworth half before having his shot palmed away by the Bedworth keeper.
His save went only as far as Evan Garnett who tapped home with ease but the linesman's flag was already raised.
Bedworth had their fair share of attacks and looked dangerous on a number of occasions.
But a solid Belper defence stopped them from creating many real clear cut chances; something that they would have wanted to get back to doing after a recent run of leaking goals.
Jack Jeys was the biggest threat for the home side; his devastating pace looked dangerous all afternoon.
The only difficult save for Mark Rathbone in the Belper goal came from Jeys.
He found himself one on one after an excellent ball forward, but Rathbone rushed out and prevented his shot expertly.
The Nailers would have been desperate to get back to winning ways after two big defeats to Basford and Shaw Lane consecutively; so a comfortable 2-0 victory was certainly perfect for Belper.
