The measured building.

countersunk_screw_diameter_detail_candidate

0.375 in

Source-local detail only. Detail appears ⅜ whereas bill clearly prints ⅞; preserve separate readings pending fabrication authority.

countersunk_screw_diameter_bill

0.875 in

Source-local detail only. Bill reading retained separately from A-A candidate; no choice of installed fastener. Review correction review-correction-20261013j-closure1011aa-img991-bill-screw-diameter: The enlarged crop of the same IMG_0991 bill row reads 3/8 in, not 7/8 in. Numerator 3 is distinct; the unchanged 620-piece CSK row and 2 in length establish the same scope.

countersunk_screw_diameter_detail_reread

0.375 in

Readable master hardware crop confirms numerator 3 and denominator 8 in A-A callout. Confirms previous candidate without choosing installed fastener.

countersunk_screw_length_detail

2 in

Second size token in A-A screw callout; no thread or installed occurrence inferred.

countersunk_screw_diameter_bill_reread_candidate

0.375 in

Master bill crop suggests numerator 3 rather than earlier 7. Lower numerator stroke is curved; this is a competing reread, not a silent replacement. Keep prior 0.875 reading and unresolved conflict until independent review confirms glyph.

bill_screw_diameter_verified_reread

0.375 in

Depicted type/component or shop-order row only; no installed quantity or accepted physical geometry. Enlarged crop clearly separates numerator 3 and denominator 8; same bill row as earlier⅞ transcription.
