How to identify this generation
- Confirm the ZX4 marking; ZX5 and ZX7 are separate heads shown in the source comparison.
- Use the linked Srixon product images to distinguish the wider ZX4 sole.
What to notice in the specifications
- The 7-iron is 28.5°, compared with 31° ZX5 and 32° ZX7 in the same ZX comparison.
- Srixon lists AW as right-hand only and notes that it was not available in Europe.
- A used set may not include the AW despite its appearance in the table.
- Every loft, lie and length row matches Srixon’s own ZX4 US product page as captured by the Internet Archive on 2021-03-06; the live page no longer exists.
Checking a club you own? These are the maker's published figures for an original build, not measurements of your club, and a source date is not the year it was made. Bending, reshafting or a hosel adjustment changes loft, lie and length, so identify the head by its own markings and have a fitter measure it when its history is unclear.
