发明名称 Bolt pattern gauge
摘要 The gauge has a plurality of laterally spaced pairs of hollowed frustrums. Each pair of frustrums is spaced in accordance with the distance between the lugs comprising standard lug patterns on existing hubs and wheels of automobiles. The hollowed frustrums may be placed over adjacent lugs on the hub of an automobile to determine the actual spacing therebetween. Furthermore, the frustrums may be inserted in adjacent openings in automobile wheels to determine that spacing and thereby enable the user to match a wheel to the hub upon which it fits.
