specs differ
Easton Deep Six 6/40 thread and Easton HIT insert differ on 4 specs: thread standard, fits, fitment rule, note.
| Spec | Easton Deep Six 6/40 thread | Easton HIT insert |
|---|---|---|
| Thread standard | 6-40 (Deep Six) | 8-32 (through the insert) |
| Fits | 4mm micro shafts fitted with a Deep Six insert; Deep Six heads only | Easton 5mm and micro shafts (Axis, FMJ); the insert sits fully inside the shaft |
| Fitment rule | Deep Six is a smaller 6-40 thread for 4mm micro shafts whose bore is too small for a standard 8-32 shank. A standard 8-32 field point will not thread into a Deep Six insert, and a Deep Six head will not thread into a standard 8-32 insert. | 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 | Few makers offer Deep Six heads, so check which insert your arrow has before buying broadheads; a standard point simply will not go in. | 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. |
