Abstract:
A method of forming an engageable member on a threadably attachable object for rotationally detaching the threadedly attachable object from securement to a threaded pedestal,the threadably attachable object being cylindrical having circular end surfaces and an annular side surface and operable to be rotated along the circular axis of the rotatable object, the circular axis concentric with the threads on the threadably attachable object, further comprising:providing a continuous, rigid, deformable planar material; defining a predetermined pattern applicable to the deformable planar material to identify a central hub portion surrounded by continuous, integral radial portions extending radially from the central hub, the predetermined pattern further indicative of demarcation lines between the central hub and each of the continuous integral radial portions, the demarcation lines further subdividing each of the continuous integral radial portions into a member side portion and an elongated leg portion; cutting the deformable planar material according to the predetermined pattern; deforming the planar material substantially perpendicularly along the lines of demarcation between the central hub portion and each of the continuous integral radial portions, the lines of demarcation defining the central hub portion as a polygon, each of the elongated leg portions extending linearly from the corresponding central hub portions of the respective continuous integral radial portion such that an edge of each of the member side portions is substantially perpendicular to the central hub portion and parallel to an edge of an adjacent member side portions, the member side portions defining a central hub protrusion for engaging a receptacle; deforming, in a substantially perpendicular manner opposed to the deforming along the lines of demarcation between the central hub portion and the integral radial portions, each of the integral radial portions along the lines of demarcation between the member side portions and the elongated leg portions such that the elongated leg portions extend radially from the central hub protrusion and substantially coplanar with the central hub portion along an end surface of the threadably attachable object, and the member side portion extending along an adjacent side of the threadably attachable object; attaching, via an attachment mechanism, the elongated leg portions and the member side portions to a surface of the threadably attachable object, the attachment mechanism for transferring rotational forces from the central hub to the threadably attachable object and resistant to shear and compressive forces opposing the attachment of the elongated leg portions to the threadably attachable object; and deforming the elongated legs at an edge around one of the circular ends of the cylindrical, rotatable object such that the elongated legs are disposed in communication with the annular side surface of the rotatable object, wherein the attachment mechanism is spot welding.
