Previously labels embedded in the soil of plant pots were easily dislodged. The invention provides a method of securing a label to the pot, but has wider applications. A sheet-like member of rigid material (4) is secured to another member (5) using a self-piercing fastener. The fastener is driven against the sheet-like member to pierce through it if it has no hole, and the other member (5) also. The fastener 1 has (1) having a shank (2), a head (3) at one end and an abutment (7) at the other to prevent withdrawal after piercing. A tool (26) for driving the fastener has an anvil (29) which is locatable in opposed relationship to a fastener driving means (28). The tool may also include retaining means (68) cooperating with back surface (67) of anvil (24) whereby one of the members, usually the sheet-like member (4), is held by the tool for movement with the anvil into the path along which a fastener is driven to thereby dissipate the driving force energy back into the tool. <IMAGE> |
