All 58 positions are loaded, giving you a full complement of pins for a 58-conductor board-to-board interconnect.
The 58-position 79425-458HLF sits in the same BERGSTIK® II family as the 56-position 79425-456HLF. The difference is two extra positions — 58 vs 56 — which matters if your BOM calls for exactly 58 circuits. The footprint is the same grid; the extra two pins just extend the row length by 0.200".
