For Vendo V-56, V-81, V-110 and Vendorlator VMC-81 and VMC-110.  Round top machines only.  Zinc plated, semi-tubular rivet.  Sold individually. 

Tip:  To install you will need a ball peen hammer and a center punch.  ( Both can be found at any hardware store).  Take the shelf and put it on a solid piece of metal with the head of the rivet down on the metal.  Take the punch and put it in the center of the rivet and tap.  This will flare the hole of the rivet out.  Once totally flared take the ball of the hammer and tap smooth.   At this point take the round head of the hammer and tap it around in a circle around the flared end to flatten it out.
