Use when a SolidCraft part needs screw holes, tapped holes, counterbores, slots, pockets or spur gears and you need starting values: clearance and tap-drill sizes, hole edge distance, web and wall minimums by process, and spur gear formulas. Reference data for the requirements, sanity and delivery checks; confirm per process before relying on it.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Holes, fasteners, pockets and spur gears: reference values

This skill holds data, not a procedure. The checks that use it live in `solidcraft-requirements-and-sanity` (before building) and `solidcraft-delivery-gate` (before delivering).

(Idea source: wzyn20051216/solidworks-automation-skill, MIT. Process values there are initial suggestions for CNC, sheet metal and plastic parts; restated here, not copied. Confirm against the real process, supplier and load.)

## 1. Decide the hole type before modelling
"An M5 screw hole" is ambiguous. State or ask which one it is, and never default it to a tapped hole:
- **Clearance** (through, screw passes freely)
- **Counterbore or countersink** (head sits below the surface)
- **Tapped** (the thread is cut in the part)

Starting diameters, mm:

| Thread | M3 | M4 | M5 | M6 | M8 | M10 | M12 |
|---|---|---|---|---|---|---|---|
| Clearance hole, ISO 273 medium | 3.4 | 4.5 | 5.5 | 6.6 | 9 | 11 | 13.5 |
| Tap drill, coarse pitch | 2.5 | 3.3 | 4.2 | 5.0 | 6.8 | 8.5 | 10.2 |

Other pitches, plastics or soft metals need the tap chart for that case; do not assume the table holds.

Tapped holes:

How to install

The exact contents, by fingerprint
mdr add randomonkey05/solidcraft-agent-skills/solidcraft-hole-fastener-rules@sha256:80f74b5b75f7e361

The line at the top of this page pins the label git:20261101.b674e1d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
