Easton HIT insert: what broadheads and points fit
What the Hidden Insert Technology insert fits, the fitment rule, and the mismatch to avoid.
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.
| Thread standard | 8-32 (through the insert) |
|---|---|
| Fits | Easton 5mm and micro shafts (Axis, FMJ); the insert sits fully inside the shaft |
| Fitment rule | The HIT insert glues fully inside the shaft so no collar sits proud of the shaft wall, giving the small-diameter shaft a strong, low-drag front end. It carries a standard 8-32 thread, so standard points and broadheads fit. |
| Note | The 5mm Axis ships with a 16-grain ST Axis HIT insert; the insert weight is part of the arrow's front-of-centre, so swapping it changes tune. |
