ABSTRACT:
An angle type power nutrunner having a housing (10) with a rotation motor, an angle head (15) with an output shaft (13), and a thread connection (21) including a lock nut (22) for securing the angle head (15) to the housing (10). The housing (10) is provided with a first group of radial holes (25) disposed in a circumferentially directed row and the angle head (15) is provided with a second group of radial holes (26) disposed in a circumferentially directed row, and a key pin is arranged to positively define alternative angular positions between the angle head (15) and the housing (10) by engaging selectively one hole each of the first and second groups of holes. The pitch of the first group of holes (25) is different than the pitch of the second group of holes (26) for enabling a small angle adjustment of the angle head (15) in relation to the housing (10).
