Abstract
A washer for accommodating the shank of a threaded bolt is formed with at least one slanted opposing face having an angle such that the lower face of a nut, threaded on the bolt, is urged into entire surface contact with the upper face of the washer, while the lower face of the washer is urged into entire surface contact with the upper surface of the article fastened to the bolt. Embodiments include an inclination angle of about 2 degrees to about 2.4 degrees, thereby providing an adequate shearing stress to the shank while concurrently providing a substantially vertical force to the upper face of the article to prevent loosening of the knot.
