I'm trying to identify and locate this part for purchase. It is from a pressure washer's pressure sensor and screws in by the plunger/spring section in the 1st image. You can see the head snapped off and it was an absolute nightmare to remove... Appreciate any help. [URL="https://imgur.com/a/RgKvCHW"]Images[/URL]

Hi folks! Recently we put something too heavy on a kitchen cabinet shelf, and two of the support pegs failed and sheared off. Problem number one is going to be getting the broken piece out from inside the hole on the cabinet wall -- it's broken off flush with the surface! Any tricks for that? Second, and more mysterious -- perusing places like Home Depot, it seems like support pegs are usually pretty standard. But I can't find any that fit our cabinet! The design of the peg is unusual, it has ridged pegs and doesn't seem to be a normal size. Unfortunately these were installed by a previous owner of the house. I took pictures of one of the pegs from different sides, and they're attached with this message. If it looks at all familiar to you and you have any leads, please let me know! Many thanks!
