For 4-40, we use 0.125" dia hole, and a 0.375" dia pad (with no SM top or bottom). This allows any locking nuts to grip something better than FR4. For 6-32, we use a 0.156" dia hole, and the same size pad (since the nots are 1/4" hex). --Bob At 05:05 PM 7/1/2003 -0500, you wrote: >does anyone have a chart of the hole size needed for the various sized >standoff? > >I need a hole for a 4-40 today, but... > >thanks > >-- >http://www.piclist.com hint: PICList Posts must start with ONE topic: >[PIC]:,[SX]:,[AVR]: ->uP ONLY!
