From the very early days Ferrari and the other Italian manufacturers used the strap or Copiglia type hose clamps. These were available in 5 or 9mm widths. Until the mid – 1960s the clamps and straps were plated with cadmium, often called Silver Cad or Cad 1. Cadmium plating is rarely seen in the U.S. becasue of the difficulty in disposing of hte plating by products. These components are all freshly plated with the correct silver Cad 1 finish. 9mm clamp and strap for radiator hoses, heater hoses.

This type of nuts were used on all of the outside-plug 250s from the time of the introduction of the GTEs through the last of the 250 Lussos. The 275 series cars changed to the flat, round, knurled nuts. Three-ear air cleaner nuts.
