<p>Abstract Disclosed herein is an apparatus for use with a threaded fastener, including: an inner sleeve member having an internal surface threadedly engagable with the fastener and a tapered external surface; and an outer sleeve member having an 5 inversely tapered internal surface rotatably engagable with the tapered external surface of the inner sleeve member. Advantageously, embodiments disclosed herein allow for an increased load bearing surface area between the inner sleeve member, which is clamped, and the outer sleeve members without increasing the overall diameter of the apparatus; a three dimensional load bearing surface area 10 rather than a conventional two dimensional plane; more efficiently and evenly distributed load stress distribution over the load bearing surface area; higher torsion strength; and apparatus with lower mass, dimensions and volume.</p> |
