specs differ
G and F nock (.166 shaft) and Pin nock and pin bushing differ on 5 specs: nock class, shaft inside diameter, fits, common names, fitment rule.
| Spec | G and F nock (.166 shaft) | Pin nock and pin bushing |
|---|---|---|
| Nock class | G / F / micro nock | pin nock over a pin bushing |
| Shaft inside diameter | .166 in | any (via bushing) |
| Fits | Micro-diameter shafts: Easton 4mm, Victory VAP.166, Carbon Express XSD | Target and 3D shafts fitted with a pin bushing |
| Common names | Easton G Small and N, Bohning F, AAE IP4, 4mm Microlite | AAE IP pin, Beiter pin, Easton pin |
| 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. | A pin nock does not seat in the shaft directly; it clips onto a metal pin bushing glued into the shaft. All pin nocks fit any pin bushing regardless of brand, so the pin, not the shaft bore, sets the fit. |
