I need to Cerakote some springs for 911 heater valves so I wanted to stretch the spring to hit every surface. Got a mounting block for two 1/4" bolts I found the other day and wanted to know the drill bit size to tap the block.
Opened google, typed in only "drill size f" that's all. and then it filled in the rest by itself. The extra weird part is I normally look for metric size. But wtf.
