Does anyone know what tool they use to screw things in with just a 1/10 inch hole in a heatsink?

I broke into this 505nm laser to replace the driver, but I'm totally unable to get enough leverage on this heatsink with just an iron nail in order to unthread the heatsink from the tube. These kinds of assemblies are really common in Chinese lasers. Does anyone know what tool they use to screw these assemblies together?

Can you show a few more pic's or a link to a similar unit?
You might have to carefully drill a small hole on the other side to have 2 points of turning it. Might have make a gizmo or one of those really pointed pliers from Harbor Freight Tools..

Hi,
If you drill another hole in the sink then you should be able to use a inside or outside retainer ring tool . It will act as a spanner wrench, also if you can apply a little WD-40 around the outer edge of the sink and let it penetrate for a while. If the sink is glued in well heat is the other alternative .

Great advice by these guys, especially for occasional use; if you were to do this often, you could also use one of these.

I've used these in the past with much success. Works when needle nose pliers don't.
