Vent Knob Vent-0004 Coutersink Degree

[rgaynor]

Hi everyone

Anyone know what degree countersink the vent knob in the fuse kit takes. It’s a #43 hole so I need to get a different die and didn’t know if it should be 82 for standard machine, 100 for aviation rivets, or 120 for blind rivets.

Thanks in advance
Rob

I just used my deburring tool. Went slow and frequently checked the fit.
