| Spec | Pin nock and pin bushing | X and A nock (.204 shaft) |
|---|---|---|
| Nock class | pin nock over a pin bushing | X / A nock |
| Shaft inside diameter | any (via bushing) | .204 in |
| Fits | Target and 3D shafts fitted with a pin bushing | 5mm shafts: Easton 5mm Axis, Easton 5mm FMJ, many 5mm hunting shafts |
| Common names | AAE IP pin, Beiter pin, Easton pin | Easton X, 5mm Microlite, Accu-Tough, Bohning A, AAE IP5 |
| Fitment rule | 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. | An X or A class nock seats in a.204-inch inside-diameter 5mm shaft. It will not hold in a.166 micro shaft and is loose in a.245 standard shaft. |
