The countersunk screw is what is standard on the HS stocks found on the LRPV and such. It does not fit the trigger guard properly, and usually damages the hole in the TG. The proper screw to use is the phillister type. I don't know why HS didn't make the stocks to use a standard screw set that Savage uses, instead of what Remington uses. I counterbored all mine to use the standard phillister type screws.
