Good morning Chuck.
According to this article some stainless is slightly magnetic:
https://www.greenwoodmagnetics.com/...nce-between-304-and-316-stainless-steel/It's not surprising that the HF Zerks are junk, is it? The only things that they have that aren't junk are zip ties and electrical tape. Quality must not be an issue for some people because HF manages to stay in business.
It's nice to know that Tractor Supply has good Zerks.
