The North Division champions beat Borders, East Lothian and Renfrewshire at Hilton Park Golf Club, Glasgow to win the title with a 100 per cent record.
Angus's last match was the hardest of the three.
They beat Renfrewshire 5-4, coming back from a 2-1 foursomes deficit to take the singles 4-2 for the match and the title.
Winners for Angus in the singles were Gillian Montieth, Claire Robertson, Jacqueline Sneddon and Ailsa Summers.
The other team members who played their part over the three days were county champion Ann Ramsay, Jackie Brown, Claire Penman and Jemma Chalmers.
East Lothian, hammered 8-1 by Angus on Saturday, completed an unhappy weekend when they lost 5-4 to Borders. South Division champions do not win many matches at the County Finals but they put 2pt on their scoreboard by taking the foursomes 2-1 and then sharing the singles 3-3 with East Lothian.
So Angus topped the table with 6pt out of six. Renfrewshire were runners-up with 3pt (one win, one draw). Borders were third with 2pt (one win) and East Lothian were fourth with 1pt (halved match with Renfrewshire on Day 1).
