99 Accord - Could sure use a quick tip
 

Help! I'm all set to replace the ignition coil on a 1999 Accord LX 4D, 2.3
4cyl.

Problem: The two screw/bolts holding the distributor cover in place seem
nearly rounded on the outside and very soft in the slots where a Phillips
screwdriver seems to belong. I'm scared to damage them but can't get either
one started at all. A 6mm wrench is too small, the 7mm slips over the
edges.

Any ideas or experieces greatly appreciated
