How to Adjust a Srixon ZX Driver: Hosel Settings & Loft Adjustment Guide
The Srixon ZX5 and ZX7 Mk II drivers use an 8‑setting adjustable hosel that changes both loft and lie together. You get ±1° loft and ±1° lie from the neutral baseline. The factory Neutral position is your starting point; Upright adds 1° loft and 1° lie for a draw bias.
Before you reach for the wrench, decide your target ball flight and check the current setting. If the club already launches too high and you set it to Upright, you will move in the wrong direction. This guide covers the hosel positions, torque spec, and real‑world settings for draw, fade, high, and low.
Quick Settings Chart
| Ring Position | Loft Change | Lie Change | Effect |
|---|---|---|---|
| Neutral (N) | 0° | Standard | Baseline – no bias |
| Upright (U) | +1° | +1° upright | Draw bias, slightly higher launch |
| Flat (position between N and U on opposite side) | –1° | –1° flat | Fade bias, slightly lower launch |
Each click on the hosel ring adjusts both loft and lie simultaneously by 0.5° increments, with a total range of ±1° in each direction. The face angle rotates approximately 2° closed in the Upright setting and 2° open in the Flat setting, which influences the starting direction at address.
Decision rule: If your current setting is already at Neutral and your ball flight is too high, do not move to Upright – that adds more loft. Instead, go one step Flat to lower launch. If you are hitting a slice and the club is already set to Upright, the problem may not be hosel adjustment; check your swing path and face alignment first before changing settings.
Step‑by‑Step Adjustment
-
Remove the screw. Use the Srixon torque wrench (T25 bit) or a compatible 3/8‑inch hex driver. Turn counter‑clockwise. Keep the washer seated on the screw – if it falls off, you will need to retrieve it or risk incomplete tightening.
-
Pull the shaft out of the hosel. It should slide free. If stuck, gently twist while pulling. Never pry with a tool – that can damage the hosel splines.
-
Rotate the ferrule ring to your setting. The ring has a small dot that aligns with stamped letters: N (neutral), U (upright). Flat positions are unmarked between N and U. To go from N to +1° upright, rotate the ring one click clockwise (looking at the sole).
-
Re‑insert the shaft. Align the shaft’s alignment notch with the flat side of the hosel. Push fully until seated – you should not see a gap between the ferrule and the hosel. If you feel resistance, the notch may be misaligned; rotate the shaft slightly until it slides home.
-
Tighten the screw to 36 in‑lbs (4.0 Nm). The Srixon torque wrench clicks at that value. If using a third‑party wrench, set it to exactly 36 in‑lbs. Do not exceed 40 in‑lbs.
-
Check alignment at address. The face should sit square or slightly open/closed depending on your setting. A draw‑bias position will close the face roughly 2°.
Verification step after tightening: Grip the head and shaft separately and try to twist them. There should be zero rotational play. If you feel any movement, the shaft is not fully seated or the screw is loose – stop and re‑seat. Also listen for a rattle when you tap the sole; a loose washer or debris inside the hosel will cause a sound that means you need to redo the assembly.
Stop/escalate threshold: If after three attempts you cannot get a snug, no‑play connection, or if the screw head is stripped (rounded hex), stop DIY adjustment. Contact Srixon customer support or a certified club fitter. Overtorquing or using a worn screw can crack the composite hosel, which is not repairable.
Common mistake: Installing the shaft without fully seating it. If you see a gap between the ferrule and hosel, you did not push it in completely. Always push it all the way before tightening.
Common Settings for Draw, Fade, High, Low
Draw Bias (anti‑slice)
- Setting: Upright (+1° loft, +1° lie)
- Why it works: Upright lie tilts the face closed relative to the path; added loft raises launch slightly.
- When to use: You consistently slice or push‑slice; you need more heel‑side contact on the face.
Fade Bias (anti‑hook)
- Setting: Flat (–1° loft, –1° lie)
- Why it works: Flat lie opens the face; lower loft reduces spin and launch.
- When to use: You hit a draw that becomes a hook; you need more toe‑side contact.
Higher Launch
- Setting: Upright (+1° loft) – or use a higher standard loft head (10.5°) if available.
- Why it works: Extra loft increases launch angle and spin.
- When to use: You struggle to get the ball airborne; you play in soft conditions or need more carry.
Lower Launch
- Setting: Flat (–1° loft) – or use a 9.5° head if you have the ZX7.
- Why it works: Reduced loft lowers launch and spin.
- When to use: You hit the ball too high; you play in windy conditions; you want more rollout.
Trade‑off: Changing loft more than 1° (by using a different head) gives a larger ball‑flight change. The hosel tweaks are subtle – roughly 3–5 yards of lateral movement and 2–3 yards of height difference. If you need more than that, consider a different head loft or a shaft change.
Torque & Tools
- Required torque: 36 in‑lbs (4.0 Nm). Never exceed 40 in‑lbs – you risk stripping the screw or cracking the composite hosel.
- Stock wrench: The Srixon torque wrench included with the driver clicks at 36 in‑lbs. If you lose it, buy a quality adjustable torque wrench with a T25 bit. Do not use a non‑torque hex key.
- Bit type: T25 (Torx Plus is not required; standard T25 works). Do not use a hex key – it can round the screw head.
- Screw condition: Check for wear. A worn screw may not hold torque and can strip. Replace with an OEM Srixon screw if needed.
Warning: If you feel resistance while turning the screw beyond the click, stop immediately. Overtorquing can crack the hosel. If a setting does not feel snug after the click, the ferrule ring may not be fully seated – re‑seat the shaft.
FAQ
Can I change the loft on a Srixon ZX driver without changing lie?
No – the hosel links loft and lie together. The only way to change loft independently is to swap the head to a different standard loft (9.5° vs 10.5°).
Will adjusting the hosel affect the face angle?
Yes. Moving from Neutral to Upright closes the face approximately 2° (making the club look more draw‑biased at address). Moving to Flat opens the face by a similar amount.
How do I know if I need a draw or fade setting?
If your miss is a slice (ball curves right for a right‑handed player), use Upright. If your miss is a hook (ball curves left), use Flat. If you hit straight already, stay in Neutral.
What is the maximum adjustment range?
The hosel offers ±1° loft and ±1° lie total. The ZX5 head comes in 9.5° and 10.5°; the ZX7 in 9.5° only. So the maximum loft you can get with a 10.5° ZX5 head and the upright setting is 11.5° effective. The minimum with a 9.5° ZX7 head and flat setting is 8.5° effective.
Can I use a non‑Srixon shaft in the ZX driver?
Yes, as long as it has a .335 tip and a compatible adapter. Srixon uses a proprietary hosel sleeve, so you need an aftermarket adapter made for Srixon/Cleveland (which share the same system).
How often should I check the torque?
Re‑torque the screw every few rounds or after a hard impact (hitting off mats or trees). Loose screws cause a rattle and can damage the hosel splines. If you hear a rattle mid‑round, stop and check the screw.
