   I agree with your assumption. But if the bolt goes completely through the   
   transducer, it cannot allow piezo (mechanical) movement in the axial   
   direction.   
      
   Note:   
   1. The non-business end is very heavy, steel or such   
   2. What you see protruding from the cone end (the "business end") is just a   
   short stud. This can be welded or otherwise adhered to whatever you want to   
   drive with this transducer and the transducer screwed onto the stud. I think   
   this stud is not the other end of the bolt head you see at the heavy end.   
   3. The bolt begins at the back (steel end) and goes... where? This is the   
   conundrum. It can't go all the way through.   
   4. The heavy end acts as the large mass (I think of it like an anchor)   
   against which the piezo works the other end (the "business end") of the   
   transducer.   
      
   But the question remains: where does the allen bolt thread into? ::
