CNC Turned Threaded Connectors

Detailed Description

Threaded ends and the internal passage work together in machined threaded connectors used between tubes, housings and mechanical fittings. CNC turning forms the bore, cylindrical shoulders and external thread, while internal threads and sealing details complete the compact connection geometry.

Hexagonal drive flats keep a wrench accessible beside the threaded joint. Inside the body, stepped bores change the available passage diameter without adding a separate sleeve. Grooves near the joint seat provide room for an O-ring or another selected sealing element.

Wrench Clearance And Sealing Location

Machined flats sit between the threaded sections and allow the fitting to turn within a crowded assembly. Narrow sealing grooves separate the mechanical fastening area from the passage interface.

Available Surface Finishes

• Nickel Plating: Frequently used for brass and steel connectors requiring corrosion resistance.
• Zinc Plating: Cost-effective protection for carbon steel components.
• Anodizing: Protective finish for aluminum connectors.
• Passivation: Enhances stainless steel corrosion resistance.

Nickel and zinc plating provide metal surface options for brass or steel fittings. Anodized aluminum and passivated stainless steel connectors use different exterior finishes without changing the connection layout.

Structural & Functional Breakdown

• Internal Thread Structure: Supports connection with male threaded components.
• External Thread Structure: Provides direct mounting into housings or mating connectors.
• Hexagonal Drive Structure: Allows installation using standard tools.
• Sealing Groove Structure: Can accommodate O-rings or sealing elements where specified.

Male and female threaded sections meet adjoining components at opposite ends of the fitting. Hex drive faces sit outside the thread envelope, leaving an exposed installation surface.

Key Features

• Controlled Thread Machining: Supports metric and imperial thread specifications according to drawings.
• Concentric Thread and Bore Geometry: Turning helps maintain alignment between connection features.
• Integrated Sealing Features: Grooves and sealing surfaces can be machined within the same production workflow.
• Custom Connector Geometry: Thread size, bore, hex dimensions and length can be customized.

Bore-to-thread concentricity places the passage around the joining axis, while localized grooves position sealing hardware beside the threaded region.

Applications

• Hydraulic Connections
• Pneumatic Systems
• Industrial Machinery
• Instrumentation Equipment
• Mechanical Assemblies

Pneumatic manifolds and hydraulic fittings often sit close to neighboring tubes, brackets and instruments. Compact connector bodies keep the threaded joint, wrench flats and internal flow route inside a small mechanical space.

Instrumentation connections can use the same stepped interior to position a mating element at a defined depth. Machined geometry serves both the flow passage and the physical joint, without requiring a separate internal spacer. Compact machined threaded connectors bring a wrenching surface and a sealed passage into the same accessible metal body.
