0.01mm Tolerance Anti-Rotation Connector Housing with Multi-Position Sealing Threads and Turn-Mill Single Setup Keyed Connector Housing
Anti-Rotation Connector Housing
,Multi-Position Sealing Thread
,Keyed Housing Turn-Mill
This anti-rotation connector housing is turn-mill machined by Dongguan Changxinda Precision Technology Co., Ltd., a CNC factory established in 2008. Keyed flats lock the housing against rotation, and multi-position sealing threads secure the connector at each indexed station. All critical features — key width, sealing thread position and bore concentricity — are held to ±0.01 mm and verified on a CMM.
Anti-rotation features solve a real assembly problem: under torque or vibration a round connector housing creeps, and the sealing thread loosens until the joint leaks. By cutting keyed flats and the sealing threads in the same setup from one datum, orientation and thread alignment stay locked together for the life of the part.
- Keyed FlatsOrientation locked, no rotation under torque
- Sealing ThreadsNPT / BSPP / UN cut in one setup
- Min Order1 piece — no tooling charge, prototype ready
ISO 9001:2015 · 6061-T6 / 7075 aluminum · CMM first-article report · NDA on request · Exporting since 2008
Each anti-rotation connector housing follows a controlled eight-stage route:
- Drawing review & DFM: STEP / IGES / SolidWorks / 2D PDF checked for key geometry, thread spec and sealing faces.
- Material: 6061-T6 / 7075 aluminum with mill certificates.
- Turn-mill programming: CAM toolpaths combining turning of the body with milling of keyed flats in one setup.
- Turning the housing: outer profile and bore machined to size and concentricity.
- Milling the anti-rotation keys: flats and tabs cut to width and angular position, locked to the thread datum.
- Cutting the sealing threads: NPT / BSPP / UN threads cut cleanly at each indexed position.
- Surface treatment: anodizing, polishing or per drawing.
- CMM inspection: key width, thread position, bore and concentricity verified with a first-article report.
The keyed housing is a starting point. We machine custom anti-rotation housings with your own key count, flat width, thread sizes, sealing face geometry and body profile — all to drawing.
We sign an NDA before engineering review, restrict drawings to the assigned programming and machining team, and never display or reuse customer geometry. Fixtures and programs built for your part stay dedicated to your program, and surplus or reject parts are scrapped on request.
Changxinda runs a plant established in 2008 with 90+ staff, multiple turn-mill lathes and 4-axis / 5-axis machining centers backed by a dedicated QC lab.

It stops the housing from creeping under torque or vibration. Keyed flats or tabs lock orientation, so the sealing thread cannot work loose and the joint stays leak-tight.
The body, keys and threads are cut in one turn-mill setup from one datum, then CMM-verified for angular position and concentricity.
NPT, BSPP, BSPT, UN/UNC/UNF and metric threads, at single or multiple indexed positions, to your drawing.
Yes — key count, flat width, tab position, thread size and body profile can all be machined to your drawing or 3D model.
Yes, before engineering review. Drawings are limited to the assigned programming and machining team and never reused or displayed.
Prototypes 3–7 days, small batches 7–14 days, mass production 14–30 days depending on complexity, with rush support available.
