Abstract
A non-magnetic locking sleeve includes an engagement unit disposed in a body which includes a locking socket and a positioning groove. The locking socket is enclosed by a plurality of peripheral walls connected one after another for holding a fastener. The positioning groove is annularly recessed into the peripheral walls for receiving the engagement unit. Preferably, an intersection of two adjacent peripheral walls forms a recessed portion whereby the fastener is held by the peripheral walls more tightly while inserting into the locking socket. A periphery of the engagement unit can be formed with a rough surface or at least one engaging surface to increase a contact area between the engagement unit and the fastener. Accordingly, the fastener is firmly positioned by the locking sleeve to increase the stability of a following fastening operation executed by the fastener.
