Reading the part number. MS17830-5C breaks down as MS17830 — the Military Standard sheet that fixes the part's design — plus the dash/suffix code 5C, which selects the exact size, material, or finish variant from the tables on that standard. Two parts sharing the MS17830 base are the same design in different variants.
