| 3 | Envelope model for assemblies: domed head of diameter A max and height H max (a spherical cap through the head's rim |
| 4 | and top), hexagon socket (nominal key size J, depth T = key engagement min, measured from the top of the head) and a |
| 5 | plain shank at the basic major diameter D of ASME B1.1 (the thread is not modelled). The head's bearing face is on |
| 6 | the XY plane at the origin, the head above it, the shank along -Z; `length` (inches) is the nominal length L under |
| 7 | the head. The model is in millimetres (1 in = 25.4 mm). |

Button head socket cap screw, inch (ASME B18.3)
Button 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:
- domed head of diameter A max and height H max, drawn as a spherical cap through the head's rim and top;
- hexagon socket, nominal key size J, depth T (key engagement, min) measured from the top of the head;
- plain shank at the basic major diameter D, length L (
length, under the head); the thread is not modelled.
The head's bearing face is on the XY plane at the origin, the head above it, the shank along -Z.
