A fastener 10 includes an apertured base 11 and a headed elongate element having fastenings 39. The head 35 of the element is captivated in a recess 25 in the base 11, as the base 11 is welded to an article 41, and the head 35 is laterally adjustable within the recess 25 after the welding operation. Complementary surface formations including for example rings 42, are formed on the base and the article to facilitate positioning of the base 11 on the article 41 during the welding operation. |
