Checking a used set? These are published factory specifications, not measurements of the clubs you own. Loft, lie and length may have changed through custom ordering or later work.
How to identify this generation
- Confirm the HL suffix and compare the head to Mizuno's JPX925 gallery.
- Do not substitute standard Hot Metal or Pro lofts; those variants share 28° 7-irons.
What to notice in the specifications
- The HL 7-iron has 3° more static loft than the standard and Pro heads.
- The pitching wedge is 45°, compared with 42° in the other two variants.
- All three 7-irons list 37.25 inches despite different loft and head designs.
What the chart cannot tell you
A loft figure alone does not predict carry distance or determine a suitable fit. Head design, shaft, strike, swing speed and delivery also matter. Check actual loft and lie with a qualified fitter when a used set's history is uncertain.
