A polymeric bobbin basket having an increased mass with a partial undercut to engage a latching mechanism on a bobbin case. A dissimilar material of greater strength and fatigue resistance than the polymeric material used in the center post is embedded within the interior of the center post less than the full extent of the center post in an arrangement that absorbs vibration and increases the strength and fatigue resistance of the center post. A shoulder spacing between the materials form the undercut.
