Review on 🔥 Easycargo 12 Pack TO-220 Heatsink + Insulator/Mounting Kits for LM317 LM317t L7805 L7812 L78XX Voltage Regulator, IRF Z44N 3205 520N 630 1404 MOSFET Transistor - Silver 20mm x 15mm x 10mm (12 Pack) by Pablo Rudon

I'm a fan of these sleek heatsinks. They dissipate heat really well. And they're badly needed when you're stepping down the voltage with components like the 7805. The only downside is the PCB mounting. If you want to mount them on a PCB you will need a small drill bit to slightly enlarge the hole for the mounting post. I used a super small hex bit to drill the hole. Just make sure the hole isn't too big. If you can keep the solder ring intact, then securing it with solder is great.
