How to set custom counterbore depth with hole tool and specified fastener?

[sprior913]

I'm trying to model a CNC waste board with replaceable MDF slats that will be surfaced flat by the CNC.  These slats are fastened by M5 hex cap bolts.  I'm trying to use the hole tool to make a counterbore clearance hole, but I need a custom counterbore depth.  The idea is to keep the max amount of material above the head of the bolt to maximize the number of resurfacings that can be done.  I'm trying to use the hole tool instead of circles in a sketch so Fusion will calculate the clearance diameter for a M5 bolt for me instead of me doing it.

When I use the hold tool and specify a flat bottom clearance counterbore hole and set the fastener to M5 socket head cap screw the option to change the counterbore depth is greyed out and can't be changed - is there any way to "unlock" that setting?

The easiest way would be to set the "Hole Tap Type" back to simple. The dialog will keep all the settings but n ow they'll be editable. Other option would be add all the holes, run press pull select New offset as the offset type then select all the bottom faces of the counterbores and set an offset.

Thanks, I tried setting the tap type back to simple and that worked great.

Setting the hole type back to simple no longer works. Any other ideas?

Still works for me. I gave another option before, add the holes then use press pull and offset the bottom face of the counterbore.
