So do the shims typically come with the master link or do they come with the riveting tool? At least it sounds like they come with the link for EK chain.
Also, are the shims metal or plastic? I was thinking that a hard plastic would probably be sufficient.
The shims are metal and they save to o-rings from getting bound in the link and prevent overtightening the link and it becoming a kinked link. Which will then lead to failure of the rivited link.
