Hi ANIBAL, These are not stainless steel they are zinc coated steel screws.
Hi River, Putting these on a cutting board is a great idea, but we don't recommend that you store it with these bumpers on top of the toaster oven.
Hi Buster - The screw extends 1/4" above the bumper.
Thank you for asking Angel18- These are great for many outdoor uses but we do not recommend these for use near high heat or flames.
Thanks for your question HB- The screws provided are approximately 3/16"w X 1/2"l. The hole size on this bumper is 3/16". A 1/4" wide screw might be a tight fit and could cause the bumper to split.
Yes they are
They lift your item slightly less than 1/2". See pic.
I only saw white and clear in the Home Depot.
