G and F nock (.166 shaft): which arrows it fits
The shaft inside diameter a G / F / micro nock fits, the shafts that use it, and the fitment rule.
Dry-fire warning
Crossbow bolt data and archery arrow spine, nock and thread data are quoted from each manufacturer's published figures, owner documentation and industry standards, cited on every page. A nock, spine or grain-weight mismatch can cause a dry-fire that damages the bow and can injure the shooter. Confirm against your own owner's manual and the arrow maker's own chart before shooting, and never drop below the stated minimum total weight.

Field notes
Fits: Micro-diameter shafts: Easton 4mm, Victory VAP.166, Carbon Express XSD.
A press-fit G or F class nock seats in a.166-inch inside-diameter micro shaft. An X or S nock is too fat to enter it, and forcing one splits the shaft mouth.
Press-fit nocks are sized to the shaft inside diameter, not the outside, so match the bore in thousandths of an inch or the nock is loose or will not seat.
