"""Hexagon socket button head screw, ISO 7380-1, M3 to M16, any length.

Envelope model for assemblies: domed head (a spherical cap of diameter dk max and height k max), hexagon socket (key

size s, depth t min) and a plain shank at the nominal thread diameter d (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; `length` is the

nominal length l, measured from under the head.

Button head screw (ISO 7380-1)

Hexagon socket button head screw, metric coarse thread, M3 to M16, at any length. Presets cover the common catalogue sizes (M3 × 6, M5 × 10, ...).

Geometry

Envelope for assemblies and clearance checks:

domed head: a spherical cap of diameter dk max and height k max (the standard's head radius is a reference value; the cap through the rim and the top is used);
hexagon socket, key size s (nominal), depth t min, flat bottom;
plain shank at the nominal thread 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

Parameter	Meaning
`size`	Thread size, M3 to M16
`length`	Nominal length l under the head, mm
`material`	`steel` (property class 10.9 / 12.9, black oxide), `stainless-a2`, `stainless-a4` (ISO 3506-1)

# Button head screw (ISO 7380-1)

Hexagon socket button head screw, metric coarse thread, M3 to M16, at any length. Presets cover the common catalogue

sizes (M3 × 6, M5 × 10, ...).

## Geometry

Envelope for assemblies and clearance checks:

- domed head: a spherical cap of diameter **dk max** and height **k max** (the standard's head radius is a reference

value; the cap through the rim and the top is used);

- hexagon socket, key size **s** (nominal), depth **t min**, flat bottom;

- plain shank at the nominal thread 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

| Parameter | Meaning |

|---|---|

| `size` | Thread size, M3 to M16 |

| `length` | Nominal length l under the head, mm |

| `material` | `steel` (property class 10.9 / 12.9, black oxide), `stainless-a2`, `stainless-a4` (ISO 3506-1) |

ISO 7380-1 hexagon socket button head screw. Envelope geometry for assemblies: domed head (dk max, k max), hexagon socket (s, t min) and a plain shank at the nominal thread 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. Dimensions from ISO 7380-1:2011 Table 1 (see the README).
