CHENGSHUO | ENGINEERING CONCEPT REVIEW Reference concept: Face-seal gland nut Page: https://chengshuoprecision.com/components/threaded-components/face-seal-gland-nut/ Our component / drawing revision: [ ] Assembly and mating interfaces: [ ] Please review: 1. Nut and mating gland/body/seal drawings showing the full assembly stack 2. Material, thread, finish and delivered-cleanliness specification 3. Quantities, traceability records and separate connection-validation procedure Sample acceptance to agree: 1. Internal thread: Specify standard, class, engagement and gauging condition. 2. Retaining shoulder: Define axial position, contact area and relationship to the thread. 3. Gland clearance: Supply mating gland envelope and assembly path. 4. Wrench access: Define flats, corner clearance and installed tool envelope. 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.
