These are replacement screws designed to fit your range. They are made of metal and are approximately ¼ inch long. They come in a package of 12. These are OEM parts sourced directly from the manufacturer.
Repair was simple (just lift off the old and put on the new). What was pleasantly surprising was how quickly I received the parts (amazing)!
Lastly, I've been looking for the correct parts/sizes in stores for years (yes, I should have tried this sooner). I was delighted to finally find a place that actually had the correct parts.
I removed old 8" surface element and terminal block. Some of old wiring had to be cut off because of harding/cracking of old wiring. Stove was 23 years old and this burner was the most frequently used one. I soldered the new and remaining old wires together. I used the shirnk wrap that came with the terminal block to cover the solder joint. I screwed the new terminal block (one screw holds it in place - used same screw from old terminal block that was removed). I finished by inserting the new surface element. Everything works fine. In the next week or two after we use it a while, I will check wiring again to make sure there are no changes. You need to be very careful as it gets very hot under the burner.
