Pin nock and pin bushing: which arrows it fits
The shaft inside diameter a pin nock over a pin bushing fits, the shafts that use it, and the fitment rule.
Dry-fire warning
Crossbow bolt data and archery arrow spine, nock and thread data are quoted from each manufacturer's published figures, owner documentation and industry standards, cited on every page. A nock, spine or grain-weight mismatch can cause a dry-fire that damages the bow and can injure the shooter. Confirm against your own owner's manual and the arrow maker's own chart before shooting, and never drop below the stated minimum total weight.
| Nock class | pin nock over a pin bushing |
|---|---|
| Shaft inside diameter | any (via bushing) |
| Fits | Target and 3D shafts fitted with a pin bushing |
| Common names | AAE IP pin, Beiter pin, Easton pin |
| 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. |
Field notes
Fits: Target and 3D shafts fitted with a pin bushing.
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.
Press-fit nocks are sized to the shaft inside diameter, not the outside, so match the bore in thousandths of an inch or the nock is loose or will not seat.
