Abstract
A hold down fastener clutching mechanism comprising an inner torque ring having a pair of split outer ring members with angled ends. A sloped surface at one of the angled ends is at a predetermined angle to the fastener axis. The other end of the inner ring member is integrally joined to an adjacent inner ring member which has a pair of rib members. The selected slope (angle) of the angled surface, for the specific material used, determines the amount of prevailing torque provided by the device itself. A pair of angled rib members protrude from the sleeve inner diameter, the angle of the rib members corresponding to the angled surface formed on the inner torque ring. The inner torque ring and the sleeve are operatively connected such that when the connecting shaft is rotated, the rib members on the inner surface of the sleeve compresses the inner torque ring to the desired preload. In one embodiment, the inner ring is a single, integral member. In a second embodiment, the inner torque ring comprises a plurality of substantially identical torque rings.
