The bottom of the sleeve is passed over the top of the bolt until the threaded portion engages the self-threading top of the sleeve.  The sleeve is turned until the proper projection is obtained.  The entire assembly is cast into the concrete, with the top of the sleeve at foundation level.  When the anchor bolt is ready to adjust, the top of the sleeve is cut off, the top is discarded.  The blot may now be adjusted within the sleeve.  Expansion or non-shrinking grout is cast into the sleeve around the bolt when equipment is set.  Other applications are done in a similar fashion.
