A torque-wrench attachment (100) comprises a chassis (140) and a wrench head (110) comprising a second longitudinal central axis (203) and a torque axis (112). The torque axis (112) of the wrench head (110) has an adjustable angle (190) relative to a first longitudinal central axis (202) of a torque-wrench handle (200). The torque-wrench attachment (100) also comprises a link (150) and a translating element (160). The translating element (160) comprises a contact surface (162). The contact surface (162) is movable along the first longitudinal central axis (202), and a moment arm (180) between the click-pivot axis (144) and a centroid (602) varies as a function of the adjustable angle (190).
