Regular shoulder eye bolts, inch (drop forged), 1/4 to 1 in: eye, shoulder, overall and thread length (dimensions only) — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/shoulder-eye-bolts-inch/ (sheet CC BY 4.0) Basis: One maker's regular-shoulder drop-forged eye bolt catalogue sheet (30 size × shank rows); dimensions only, no load values Catalog version: 2026-10-20 Sizes: see table below - Rows are the Chicago Hardware regular-shoulder pattern as printed: nominal thread size × shank length, outside eye C, inside eye D, overall length E, outside shoulder F, shoulder thickness G and thread length T (inches). Each size has one set of eye and shoulder dimensions, with several shank lengths; the thread length is per row. The sheet's 7/8 x 5 thread length prints as 2-12 followed by an inch mark and reads as 2-1/2 in against the neighbouring rows. - Working load limits, weights and part numbers are left out on purpose: a lifting figure should come from the marking on the eye bolt, not from a dimension page. The sheet names an ASME standard for its requirements but the number is not legible in the text read, so no standard is cited for these dimensions. - These are one maker's dimensions; other makers' shoulder eye bolts differ in eye size and shoulder. The sheet notes special shank and thread lengths are available. - Not published as numbers: the eye cross-section, the neck blending eye to shoulder, thread form. No file is drawn.
