Thanks, @snwcmpr I understand your point and the importance of patience. In this case, however, the screw has nothing for the driver to grip. So even after the penetrating oil does its job, I still have to bust out the screw most likely (if the ScrewGrab doesn’t work). I have 4 replacement screws ordered from OCP luckily.
That screw doesn't look far off from one had to deal with on a 530. It was stripping like that, but I didn't want to give up and penetrating oils weren't working for me. I took the stove to Lowes and got the largest blade screwdriver they had that filled the slot. With it, I was able to grab enough of the screw to remove it, but it still required patience and downward force while unscrewing.
Thank you, @Jim Lukowski I have the largest screwdriver that will fit. Ha. Built for engine work. The ScrewGrab product should arrive on Friday, so I’m hoping for the best.
You don't want to hit the area too hard, or the fount will easily dent. I have a 530 that had a screw like that and have a dented fount as a result. I took a dremel tool and cut a groove in there and removed the screw that way.
@redspeedster Thank you for suggesting ScrewGrab!!! Andrew: 1 Stripped Screw:0 This stuff really works! Now, I’m going to install the 4 new screws I received today from OCP. They also came with lock washers too.
Compare the length of the old and new screws in case you need the washers to prevent the screws from punching through the tank/fount.
@Jim Lukowski Thanks for the advice. I screwed them in with the washers, before I read this. Next time I disassemble the stove, I’ll check.
