Answer to: What type of screws are used in easy bake overns model#93404Ok sounds like yours is the same as ours ... and we did the same thing ... cake rose too high... cake everywhere. I did a google search for the model number you supplied and the majority of the pics coming up look like ours. It's a side pass through load oven. Anyways back to the original question... it's a torx screen driver bit. But one member suggested getting the driver set that iFixit has... that won't work. I have that driver set and it won't reach down to the screws as the hole is too narrow and deep. Even had a extension that works with their driver set and that is too fat for the hole. Best suggestion is go to the hardware store and bring the oven with you and find the screw driver section and find one that fits.
