(2nd link is for shortening the shoulder length on an 8mm shoulder (8mm shaft))

Shoulder bolts are used for mounting bearings among other things, don't see why they wouldn't work, unless you are referring to the OD of the shim being to large to fit inside a recess.

Doesn't really matter as AMAIN has them cheaper, just wondering wondering why the shortening shims for an 8mm shoulder wouldn't work.

That said, I've not seen those shoulder screw shims before. Cool to know they are available.

(I tossed the lengthening shims in there because I didn't know if it was an 8mm screw or 8mm shaft.

Steve - I was noting the OD size of the McMaster shim. I think that OD is a touch too large to clear the inner edges of the outer race.
