<p>An improved machine screw (611) for engaging a correspondingly threaded aperture. The screw includes a head (613) and a threaded shank (615) having proximal (617) and distal (619) portions. The shank has a slot (623) dividing it into at least two legs (629) such that it is deformable from a first position enabling the screw to be easily inserted into the aperture and, to a second position enabling the screw to hold secure within the aperture.</p> |
