Abstract
The present invention is concerned with improvements to removable fasteners and is particularly related to removable and re-usable fasteners for use in wet-fit applications, such as joining components that include a sealant or adhesive. A dowelling fastener (200) is provided having a head end and an insertion end and a cylindrical dowelling portion, wherein the fastener is provided with a plunger (204) at the insertion end for clearing material from a hole as the fastener is inserted into the hole, wherein the plunger is rigid and has a circular cross section with a diameter substantially the same as the dowelling portion of the fastener, the plunger tip thereby being a close fit with the hole. The plunger of the present invention is intended specifically for clearing materials from the bore and therefore has other features optimised for this purpose, including ridges around its periphery.
