Yes. a little heat made them come out easier.

Peter, for future reference they are not, "Normal", philips head screws. They are JIS (Japanese) screws.
A no'2 JIS screwdriver should have a better result.

   Exactly. It is even labeled to tell you not to use a conventional Phillips head, note the dot impressed on it.

    I just tried it on a brand new in box 46LA, to me it is beyond conception that it could strip out the head, it is more secure than any Allen screw I have ever used - including the one where I nearly stripped the head on the Allen screw on a 40VF the other day. The screws aren't that soft, it's the 4 $5 screwdriver that everyone steadfastly refuses to use.

   The correct size JIS driver to use is a #2, that is the correct driver for all 8 screws.

     I also tried various Craftsman and Proto Phillips screwdrivers, A #2 Craftsman will go in there and have a *chance*, but it is not all the way in the slots. Note that it looks comically too large just looking at it, the shaft is 2x or more diameter of the screwhead.  Any #1 Phillips I have will not work and is *very likely* to strip, since the point bottoms out before the slots are fully engaged.

   A good check is whether you have any residual slop. The #2 Craftsman Phillips will go back and forth a few degrees. The #1 Phillips will rotate back and forth maybe 30 degrees, that is the indication that it WILL NOT WORK. The JIS #2 (Hozan or Vessel) has *zero* slop, and I mean, none at all, it is fully tight and cannot rotate any at all.

    Note that this is the almost the same situation with flat screwdrivers. There should be nearly no slop in rotation, if there is, you will at least damage the slots, it might work, but the key to good workmanship is that you can work on it and leave no "technician traces", it still looks new when you are done.

Learning about JIS screw drivers 30 years ago would have saved a lot of grief on my Honda's, Kawasaki's and Yamaha motorcycles

To continue furiously flogging this dead horse, the is an illustration of the problem:



   Note that not only is the proper driver much more blunt, it is also a different angle and much thicker individual blades. The point on the Phillips bottoms out in the screw and does not allow the individual blades to reach to the ends of the slots. That, and the fact that the blades are far too narrow to make contact all the way across, makes the pressure where it does touch much much higher for a given amount of torque, basically is it touching at best on just the edge, and then on a small part of the edge.

    The proper driver makes contact from the bottom all the way to the edge, and completely fills the slots, greatly lowering the pressure on the interface.

   The high local pressure is what causes the metal to yield. I checked with my hardness files, and the OS screws in the 46LA are about as hard as the Allen cap screws that come in the 40VF. The problem is not the metal, is it creating high local pressures that damages the slots.

    OF course, with this knowledge, you could, if you were pretty careful, grind a Phillips driver to the same shape as the JIS. Not only do you take off the point, you have to grind the blades at a slightly different angle, and far enough up the shaft to catch the blade as it widens out. Unfortunately, that also makes it catch the slot up on the curved part of the blade cutouts, so you still have a problem, just not as big a problem as before.

   But of course, once you note that you can get the right screwdriver fo $5 in a few days, that all begins to look like a lot of work that you could avoid, and do something useful instead.

Thanks guys, and yes they are not your philips head. I just forgot the name (JIS) I first tried a JIS driver, \

    If it stripped out, you had *too small a driver*. It *will not* strip if you use the right drivers, it would break the head off the screw completely before the screwdriver slipped. As evidenced by the fact that you got a larger one to fit after the first attempt - the right driver, the one and only right driver, is the biggest one that can possibly fit.

   It is absolutely no mystery why we have so many "why won't my engine run right?" threads.

Once you have converted to socket heads, don't go crazy tightening.  Don't ask how I know this.
