These are exactly as advertised so if you need small heatsinks and thermal adhesive they are perfect. I use them to set up some easydriver stepper motor drivers. However, I could see that they work fine on Raspberry Pi or VGA Ram as stated in the description. Pay attention to the dimensions, for some reason I thought they were 10mm when I ordered them (I haven't actually checked) but was pleasantly surprised to find 14mm. Perfectly fine for my use case, but in case, like me, you've just seen the picture and made a guess.
