Socket head cap screw, inch (ASME B18.3)
Hexagon socket head cap screw, 1960 series, Unified inch threads (UNC and UNF) #0-80 to 1/2-20, at any length. Presets cover the common catalogue sizes (#4-40 × 1/2, 1/4-20 × 1, ...).
Geometry
Envelope for assemblies:
- cylindrical head, diameter A max, height H max;
- hexagon socket, nominal key size J, depth T (key engagement, min), flat bottom;
- plain shank at the basic major diameter D, length L (
length); 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.
Parameters

ASME B18.3 hexagon socket head cap screw (1960 series), Unified inch threads #0-80 to 1/2-20. Envelope geometry for assemblies: head (A max, H max), 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 bearing face is on the XY plane at the origin and the shank points along -Z; `length` is the nominal length under the head, in inches (the model itself is in millimetres). Dimensions from ASME B18.3 Table 1 (see the README).
