Abstract
A bush for installation in easily crushed or marred work material such as apertured honeycomb sheet or fibre reinforced plastics material, enables the work material to be secured to a support, by means of a nut and bolt, without damage. The bush has a cylindrical body longer than the thickness of the work, and a flange for abutting a face of the work at one end of the body. The other end of the body has an annular boss which projects beyond the other face of the work, and, peripherally of the boss an annular skirt which during installation can be deformed to provide a retaining flange for engaging the other face of the work. A bolt can then be passed through the bush and a support, and secured with a nut. Only the bush directly engages the work.
