Abstract: The purpose of this invention is to retain an abhor nut to a power tool while the nut is not in use. More specifically it is intended to keep the abhor nut of an angle grinder attached to the grinder. Grinding abrasives for an angle grinder can be purchased with or without a center hub. The abrasives that do not have a center hub make use of the abhor nut to secure them to the grinder. When an abrasive with a center hub is used on the grinder the abhor nut is not needed. The nut is removed from the abhor and frequently becomes misplaced. This invention keeps the grinder and nut together while the nut is not being used. This is designed for angle grinders, but could be used for other power tools and machinery.
