+# Threaded Hole Creation Atomic Skill
+
+## When to use
+
+- A part needs an internal thread, tapped hole, threaded mounting hole, or screw hole with a specified metric/imperial size.
+- The request mentions M3, M4, M5, M6, M8, M10, tapped hole, threaded hole, or thread depth.
+
+## Do not use when
+
+- The feature is an external thread on a bolt, screw, or shaft.
+- The hole is only a smooth clearance hole.
+- The model should avoid thread geometry and only show a simple bore unless the prompt asks for thread detail.
+
+## Recognition features
+
+- SolidWorks evidence such as HoleWzd threaded hole or thread parameters.
+- Descriptions mention fastening, tapped holes, internal thread, or screw mounting.
+- Hole is located on a planar face, boss face, or shaft end face.
+
+## Core invariants
+
+- Use a standard threaded hole feature or thread callout when available.
+- Keep the threaded hole axis normal to the placement face unless angled threading is requested.
+- Separate tap drill diameter, nominal thread size, hole depth, and thread depth.
+- Keep enough wall material around the threaded hole.
+- Add lead-in chamfer after the thread/hole is placed.
+
+## Parameter roles
+
+- `thread_size` defines nominal size such as M3/M4/M5/M6/M8/M10.
+- `thread_pitch` defines fine/coarse pitch when specified.
+- `thread_depth` defines threaded length.
+- `hole_depth` defines blind hole depth if not through.
+- `placement_point` and `face_normal` define location and direction.
+- `lead_in_chamfer` defines assembly entry.
+
+## Construction sequence
+
+1. Select the planar face or end face for the threaded hole.
+2. Place the hole center from datums, centerlines, or axis references.
+3. Create the hole using a threaded HoleWzd/hole feature with size and depth.
+4. If the backend cannot model threads, create the correct pilot bore and preserve thread intent in naming/comments.
+5. Pattern or mirror the threaded hole feature when repeated.
+6. Add a small lead-in chamfer after the threaded feature is stable.
+
+## Common failures
+
+- Modeling a threaded hole as a plain through cylinder.
+- Creating external thread geometry on an internal hole.
+- Placing threaded holes too close to edges, slots, or pockets.
+- Forgetting blind depth or thread depth.
+- Adding visual helical threads that make the model heavy or fragile when a callout is enough.
+
+## Evidence summary
+
+- Latest run evidence: 87 accepted atomic insights matched threaded/tapped hole creation.
+- Strong repeated names include `create_threaded_hole_with_hole_wizard`, `create_threaded_hole`, `threaded_hole_placement`, and `use_hole_wizard_for_threaded_holes`.
+- Frequent operations in the latest run: HoleWzd, Cut, RevCut, Chamfer, Pattern.
