S and Super nock (.245 shaft): which arrows it fits
The shaft inside diameter a S / Super 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.
| Nock class | S / Super nock |
|---|---|
| Shaft inside diameter | .245 in |
| Fits | Standard 6.5mm shafts: most Easton 6.5mm and Carbon Express shafts |
| Common names | Easton S, Super, 6.5mm Microlite, 3D Super, Black Eagle STD, AAE IP6 |
| Fitment rule | An S (Super) nock seats in a.245-inch inside-diameter standard shaft. It is a hair smaller than a GT nock, so it is loose in a.246 Gold Tip shaft and can fail there. |
Field notes
Fits: Standard 6.5mm shafts: most Easton 6.5mm and Carbon Express shafts.
An S (Super) nock seats in a.245-inch inside-diameter standard shaft. It is a hair smaller than a GT nock, so it is loose in a.246 Gold Tip shaft and can fail there.
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.
