lot of 5 High end surplus terminals or test points , Rare? Here is what we observed about them: Gold plated Package was marked Cambion 450-3029 They are 30mm long (29.9 mm) (1.18 inch) The long squared part is wire wrap style BUT is 1mm, so wider than standard wire wrap tool, so either hand wrap or find specialized tool? or solder to. The "through hole" round portion looks to be 2.2mm diameter The very top test point or socket is 1.7mm outer diameter with hole in center , not sure of diameter of hole but fits standard component leads such as on a resistor or capacitor if you wanted to solder one into it. Bid is per 5 QTY1= 5 pins QTY2= 10 pins etc Shipping combined so stock up and save
