end caps on range were cracked

I was surprised to find that the 2 screws holding on the plastic end caps were not philips. it looked like an allen wrench deal but that didn't work. Turned out that I had to buy a hex tool. Looked kinda like a swiss army knife but had allen wrench like hex tools in various sizes. By then I was determined to finish the job even if it meant buying a tool I'd never use again. The job took about five minutes once I had the right tool. The stove looks normal now. The stove looks brand new but for some reason there were cracks in the end caps where the screw hole were.
