| 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. | 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. |
