| 3 | Envelope model for assemblies: 82 degree countersunk head of diameter A (theoretical sharp, max), hexagon socket |

Flat head socket cap screw, inch (ASME B18.3)
Flat (82° countersunk) head socket cap screw, Unified inch threads (UNC and UNF) #0-80 to 1/2-20, at any length. Presets cover the catalogue sizes.
Geometry
Envelope for assemblies:
- 82° countersunk head of diameter A (theoretical sharp, max); its height follows from the head angle, (A - D) / 2 / tan 41°, which is the table's reference head height;
- hexagon socket, nominal key size J, depth T (key engagement, min);
- plain shank at the basic major diameter D; the thread is not modelled.
The head's top face is on the XY plane at the origin and the screw points along -Z. length is the overall
length L (head included), as flat head screws are specified.

ASME B18.3 flat countersunk head socket cap screw (82 degree head), Unified inch threads #0-80 to 1/2-20. Envelope geometry for assemblies: countersunk head (A, theoretical sharp), hexagon socket (J, T min) and a plain shank at the ASME B1.1 basic major diameter; the thread itself is not modelled. The head's top face is on the XY plane at the origin and the screw points along -Z; `length` is the nominal overall length, in inches (the model itself is in millimetres). Dimensions from ASME B18.3 flat head table (see the README).
