I looked at many "solid brass" options that started at $20 per unit and went up from there. I needed 46 of them! These are zinc and have a gorgeous dark brass brushed finish that look elegant on my white cabinets.  I also needed something to cover the enlarged holes (drilled to accommodate 3 3/4 pulls in the past) and these did nicely.  
Had no problem fitting them although had to use different machine screws as some of my drawers are super thick. Was waiting for the backordered matching knobs but these looked so good mounted vertically, I ordered another 20.
