Meanwhile, Ystrad Rhondda notched their fifth in a row with a 29-20 home win over Narberth. Four second half tries carried them to a bonus-point triumph after they had trailed 12-5 at the break.
Alex Webber crossed in the first half and then Jarrad Llewelyn, twice, Corben Evans and Josh Llewelyn added further tries. There were also two conversions from Rhys Trulove and Williams.
The Welsh All Blacks ran in inne tries in a totally dominant display to remain in the top two promotion places. They have played two more matches than unbeaten table-toppers Pontypool, and also two more than third place Bargoed.
But their 11-point advantage over the Bulls means that not even two bonus-point wins will be enough to haul them into the promotion places at present.
Both wingers James Roberts and Llewellyn Hawkes scored two tries each, as did captain and centre Ryan Evans. Full back Lewis Evans, scrum-half Luc Jones and prop Tim Ryan also crossed once.
Neath led 47-0 at half-time but were only able to add 12 more points after the break. They lost Elis Hopkins to a yellow card and also suffered a string of minor injuries.
Bargoed also picked up a bonus-point in their 24-11 triumph at Bedwas, bagging two tries in each half in tricky conditions. The home side stayed in touch in the first half, a Rhys Morgan try and two James Dixon penalties keeping them within three points at the break.
Beddau were also among the tries at Mount Pleasant Park as they beat Tata Steel 52-19. It was 24-5 at half time, with Adam Ashurst releasing James Davies to run in the bonus-point try on the stroke of half-time.
Beddau added 26 points after the break, with Ewan Roberts going on to record his hat-trick. The visitors notched three tries of their own.
In Division 1 East Central, Porth Quins made their second visit to Cardiff in a week as they beat Rhiwbina 31-21. Dunvant stayed in the promotion race in Division 1 West Central thanks to a 29-18 home win over Nantyffyllon, and Kenfig Hill moved to within two points of the third and final promotion place with a 19-10 home win over Bridgend Athletic.
Llangennech threw open the title race in Division 1 West with a notable 36-21 home win over Newcastle Emlyn. That moved them up into third place and they have two games in hand on the two teams above them.
They are due to face unbeaten top of the table Crymych on 1 April in a vital fixture.
