Abstract: The invention provides a bolt or stud mounting and extracting tool having a tool body with a stud receiving recess therein that includes a longitudinal axis which is parallel during operation with the stud that is being removed. The recess has an oval interior which is smoothly contoured internally. The recess is free from multiple diverging pockets separated from one another by centrally projecting shoulders, making it easy to manufacture. The oval interior of the tool is elongated transversely on a lateral axis perpendicular to its longitudinal axis. The recess has a concave stud-engaging contact surface at one end of the lateral axis that engages an extended portion of the stud and a second concave roller-engaging surface at the other end of the lateral axis to engage a gripping roll aligned with the stud in the recess. The roll-engaging surface is contoured to force the gripping roll against the stud when the tool is rotated about the stud. The recess is closed at one end. A curved channel in the closed end of the recess receives one end of the roll and a retaining plate at the open end of the recess holds the roll in place.

Abstract: A wrench suited for retaining a wheel lug nut in place during removal of a broken wheel stud or lug bolt of a vehicle. The tool comprises an elongated wrench body with upper and lower opposing faces. A polygonal opening is provided at one end to receive the nut and extends all the way from the lower to the upper face of the tool. The tool includes a retaining head located at the opposite end of the tool from the opening. The retaining head is secured to the lower face of the tool and has at least one upwardly facing laterally extending shoulder. Each such shoulder has an upwardly directed face adapted to underlie the inner edge of the wheel rim when the tool is in use with the opening mounted upon the wheel lug nut to help hold retain the tool in place during use.
