| Spec | H nock (.234 shaft) | Pin nock and pin bushing |

| Nock class | H / H.E. nock | pin nock over a pin bushing |
| Shaft inside diameter | .234 in | any (via bushing) |
| Fits | Shafts with a.234-inch inside diameter | Target and 3D shafts fitted with a pin bushing |
| Common names | Easton H and H.E. class nocks | AAE IP pin, Beiter pin, Easton pin |
| Fitment rule | An H or H.E. class nock seats in a.234-inch inside-diameter shaft, between the 5mm X-nock bore and the standard S-nock bore. | 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. |
