specs differ
G and F nock (.166 shaft) and S and Super nock (.245 shaft) differ on 5 specs: nock class, shaft inside diameter, fits, common names, fitment rule.
| Spec | G and F nock (.166 shaft) | S and Super nock (.245 shaft) |
|---|---|---|
| Nock class | G / F / micro nock | S / Super nock |
| Shaft inside diameter | .166 in | .245 in |
| Fits | Micro-diameter shafts: Easton 4mm, Victory VAP.166, Carbon Express XSD | Standard 6.5mm shafts: most Easton 6.5mm and Carbon Express shafts |
| Common names | Easton G Small and N, Bohning F, AAE IP4, 4mm Microlite | Easton S, Super, 6.5mm Microlite, 3D Super, Black Eagle STD, AAE IP6 |
| Fitment rule | 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. | 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. |
