Do any PCB packages allow you to add countersunk holes to a PCB rather than plain ones or will I just had to do it myself?

What I have seen is multilayer pcbs with different cutouts on different layers, this could be adapted as a countersink

I am not using it as a panel but the problem does involve a front panel. The original design uses a 2.5mm pan head screw to fix the PCB to a die casting that in turn attaches to the front panel. The die castings have become expensive so I have replaced them with a simple standard pre tapped blocks. However the block have a 3mm tap for the part that attaches the PCB. No problem in principle but the pan head is taller and now extends beyond the edge of the front paneland could interfere with adjacent modules. A countersunk screw will fix this.warpie said:Why countersunk? Will you use it as a panel?
Perhaps a button head? Lower profile than pan head, they usually take an allen driver. Sometimes used to fasten console faders to the surface, prettier than pan head screws.ruffrecords said:.

I think you want low profile head socket cap screws. At least this is what I think you would see in a professional product in this scenario.ruffrecords said:... the pan head is taller and now extends beyond the edge of the front paneland could interfere with adjacent modules.

Gold said:I was going to suggest a low profile socket head screw also. I use those to attach the faceplate to Par Metal chassis. Mostly because I like the way they look but also because they are low profile.
