Nuts and Bolts was a weekly television drama series, set in the fictional South Wales town of Ystrad. It began airing in 1999 on HTV. It ran for three years until it was cancelled in 2002. Filmed entirely on location in Merthyr Tydfil, the series made large use of exterior locations, with many interiors being recorded in a former Welsh Water depot; which became a hastily improvised television studio.
