Abstract
A wheel-balancing weight mounts to a wheel with a flange. The weight includes a body and a clip. The body is stamped by a punch to define a pocket within which an attaching portion of the clip resides. The defined pocket has a planar base and opposing side walls generally perpendicular to the base. The body as stamped by the punch includes a pre-stake for each side wall external to the pocket and adjacent the side wall, and an undercut for each side wall within the pocket and generally located at a juncture of the side wall and the base.

A wheel balancing weight for mounting to a wheel with a flange, the weight including a body and a clip, the body for providing a predetermined mass to the weight and the clip for grasping the flange to secure the weight thereto, the body having an attaching face and a pocket defined in the attaching face within which an attaching portion of the clip resides, the defined pocket having a planar base and opposing side walls generally perpendicular to the base, the body also including a pre-stake zone in the attaching face generally external to the pocket and adjacent each side wall, the body further including an undercut defined within the pocket adjacent each side wall, each defined undercut being generally located at a juncture of the respective side wall and the base,
- each pre-stake zone including a securing ridge of material over an adjacent edge of the attaching portion of the clip resident within the pocket, each pre-stake zone also including an enlarged notch in the attaching face, the securing ridge and the enlarged notch of the pre-stake zone following a respective side wall thereof, the securing ridge being immediately adjacent the respective side wall and being bordered on one lateral side thereof by the respective side wall and on the other lateral side thereof by the respective enlarged notch, each enlarged notch having a V-formation in cross-section, the securing ridges in combination securing the attaching portion of the clip to the body.
A body for a wheel balancing weight for mounting to a wheel with a flange, the weight including the body and a clip, the body for providing a predetermined mass to the weight and the clip for grasping the flange to secure the weight thereto, the body having an attaching face and a pocket defined in the attaching face within which an attaching portion of the clip is to reside, the defined pocket having a planar base and opposing side walls generally perpendicular to the base, the body also including a pre-stake defined in the attaching face adjacent each side wall, each defined pre-stake being external to the pocket, the body further including an undercut defined within the pocket adjacent each side wall, each defined undercut being generally located at a juncture of the respective side wall and the base,
