A cap (16) and a method of installing the cap to form a sealed cavity (20)around an end of a fastener (10, 14, 40), which passes through a structure (11). The cap (16) comprises a body portion forming a central cavity (20) and a circular cylindrical base (18), and an annular flange (21) which extends outwardly from the body portion. The body portion is deformable between a first configuration in which the annular flange (21) is inclined upwardly, and a second configuration in which the annular flange (21) is inclined downwardly. The method comprises: applying a quantity of sealant (23) to the annular flange (21) in the first configuration; fitting the cap (16) over the end of the fastener so that the fastener is enclosed by the cap; and turning down the annular flange (21) such that the cap assumes the second configuration in which an annular pocket (24) is formed between the flange (21) and the base (18), and the sealant material (23) fills the annular pocket (24); and bonding the cap (16) to the structure (11) with the sealant material (23).
