Abstract

The invention provides a plug and fastener (10, 110, 210, 310, 410, 510, 610, 710, 810, 910, 1010, 1110) and method for sealing in an opening (20) in a workpiece (P). The plug and fastener includes a shank (12) having a threaded portion (14, 114, 214, 314, 414, 514, 614, 714, 814, 914, 1014, 1114) for engaging with an internal wall (18, 118, 218, 318, 418, 518, 618, 718, 856, 856a) of the opening and providing a first seal, and includes an unthreaded sealing portion (16, 116, 216, 316, 416, 516, 616, 716, 816, 916, 1016, 1116) proximate the threaded portion which also enters the opening. The unthreaded sealing portion is configured to engage and provide a second seal against the internal wall (18, 118, 218, 318, 418, 518, 618, 718, 854, 854a) of the opening.
