When fastened to the scanner body subassembly, {HEAD ~ the flexures} may deflect slightly out of their planes by {TAIL ~ some small amount}, thus compensating for mechanical tolerances, however, the attachment to the scanner body subassembly will not affect the load on the alignment features, and once fastened, the clamped areas around the screw will bear any shock loading without deformation
