CHENGSHUO | ENGINEERING CONCEPT REVIEW Reference concept: Bulkhead connector shell Page: https://chengshuoprecision.com/components/housings-and-enclosures/bulkhead-connector-shell/ Our component / drawing revision: [ ] Assembly and mating interfaces: [ ] Please review: 1. Shell drawing with panel, insert and locking-hardware interfaces 2. Material, thread, surface treatment and controlled orientation 3. Quantities, dimensional records and separately defined complete-assembly tests Sample acceptance to agree: 1. Panel seating: Define shoulder position, panel thickness and cutout relationship. 2. Insert location: Tie bore and internal shoulder to the agreed mounting datum. 3. Orientation: Control the flat or key feature relative to insert geometry. 4. Finished connection: Specify thread engagement, tool access and finish allowance. Material grade / finish: [ ] Sample / production quantities: [ ] Target timing / delivery destination: [ ] AI-generated engineering concept, not a production photograph or completed delivery. Feasibility, process route and acceptance criteria require review of our actual drawing.
