Buxton won a place in the FA Cup second qualifying round for a ninth consecutive season after a 2-1 win over Ramsbottom United.
Taking on bottom-placed Rambsbottom United, the third-placed Bucks looked capable of a big win early on and took a lead in just the third minute.
After powering a 19-yard free-kick at keeper Shenton, top scorer Liam Hardy earned a penalty kick in the next attack.
Fed by Bradley Barraclough, he was unceremoniously tripped and, though hurt, rose to hammer home his fourth spot-kick in a month.
The Bucks should have doubled their advantage only three minutes later as Hardy set up Ash Burbeary 10 yards out, but an unexpectedly heavy touch denied him.
Ramsbottom responded well to show a surprising degree of attacking intent as they scored an offside goal on 12 minutes and equalised on 19 minutes.
Experienced marksman Lee Gaskell fastened onto a long ball down the middle as the home defence plainly missed the leadership of the not fully recovered Greg Young.
The rest of the half was evenly contested with Hardy having a narrow-angled drive well-saved by Shenton and Barraclough hitting the inside of a post just prior to half-time.
At the other end midfielder Heron wasted a good opening with a tame shot at Phil Barnes.
The Bucks attacked purposefully after the interval and worked a fluent move up the right and Glenn Beleziki’s low cross passed just ahead of the onrushing Hardy.
The important second goal came in unexpected fashion just short of the hour.
Beleziki did the initial spade-work in central midfield, before the ball reached Barraclough, whose less than fierce shot to Shenton’s near-post squirmed out of the otherwise excellent keeper’s grasp and over the line.
Substitute Alex Wiles then added a new dimension to Buxton’s play up the right and from his low ball in, Barraclough fired just wide of the near post.
Tom Buckley and man-of-the-match Ricky Ravenhill created Barraclough’s next opportunity, but midfielder Meaney did well to thwart him while Shenton made a fine low save to deny Buckley’s well-struck 19-yard free-kick.
Buxton (4-4-2): Barnes; Beleziki, Gascoigne, Bembo-Leta(J),Green; Burbeary(Wiles), Ravenhill, Burrell,Buckley; Barraclough, Hardy.
