Custom 304 Stainless Steel CNC Turned Threaded Flange Component
Product Overview
Custom 304 Stainless Steel Threaded Component
This component is manufactured from 304 stainless steel using CNC turning processes to create the cylindrical body, external thread profile, internal bore and flange-style head.
The stepped geometry provides multiple functional surfaces within a compact component. The threaded section is designed for secure mechanical engagement, while the machined head provides a larger contact area for installation or positioning.
Rather than offering this as an off-the-shelf fastener, we manufacture the component according to the customer's CAD drawing, sample or engineering specification.
Thread size, pitch, bore diameter, flange dimensions, overall length and tolerance can all be customized to suit the final assembly.
304 stainless steel is a practical choice where the component needs a combination of corrosion resistance, mechanical strength and clean metallic appearance.
Key Product Features
Engineered for Custom Mechanical Assemblies
304 Stainless Steel Construction
304 stainless steel offers a useful balance of corrosion resistance, strength and machinability for general industrial components.
CNC Turned Thread Profile
The external threads are produced as part of the CNC turning operation, allowing thread dimensions and pitch to be matched to the customer's drawing.
Machined Internal Bore
The hollow center is suitable for applications requiring clearance, passage, mating or integration with another component.
Integrated Flange Head
The enlarged head provides a defined seating surface and can be customized in diameter, thickness and profile.
Drawing-Based Production
We manufacture according to 2D drawings, 3D CAD models, samples or specified dimensions rather than limiting customers to standard catalog sizes.
Prototype to Production
Suitable for prototype quantities, engineering validation, small production runs and repeat OEM orders.

Manufacturing Process
How We Produce This Stainless Steel Turned Part
304 stainless steel bar stock is prepared according to the required component dimensions and production quantity.
The workpiece is accurately positioned in the CNC lathe before turning the outside diameter, flange profile and stepped sections.
The center bore is drilled and machined to the required diameter and depth.
The external thread is cut according to the specified thread standard, pitch and dimensional requirements.
Sharp edges and machining burrs are removed from the threaded and non-threaded surfaces.
Additional finishing such as polishing, brushing or passivation can be arranged when required by the application.
Critical dimensions, thread engagement, bore dimensions and overall appearance are checked before shipment.
Why 304 Stainless Steel?
Why Engineers Choose 304 for This Type of Component
For general-purpose mechanical components, 304 stainless steel is often selected because it combines:
- Good corrosion resistance
- Good mechanical strength
- Clean metallic appearance
- Good availability
- Suitable machinability
- Wide industrial application range
For more demanding corrosion environments, alternative stainless steel grades can also be considered. Your factory's existing material range includes 304, 303, 316 and 316L, so this product page can naturally create an upgrade path instead of forcing every buyer into 304.
Applications
Where Can This Custom Turned Component Be Used?
Depending on the final drawing and thread specification, similar components can be used in:
Important: Because the exact application cannot be determined from the photographs alone, I recommend using "suitable for" rather than claiming that this specific part is a hydraulic fitting, medical component or pressure-rated connector.
That will make the product page more credible.
Customization Options
Need a Different Thread or Geometry?
We can customize the component according to your engineering requirements.
Available customization includes:
- External thread diameter
- Thread pitch
- Metric / Imperial thread
- Internal bore diameter
- Overall length
- Flange diameter
- Head thickness
- Shoulder dimensions
- Chamfer dimensions
- Surface finish
- Stainless steel grade
- Marking / engraving
If you already have a drawing, simply send the 2D PDF + 3D STEP/IGES file for quotation.
Your existing website also accepts formats such as STEP, IGS, XT, DXF/DWG and PDF, so retaining this purchasing path is consistent with your existing manufacturing workflow.
Quality Control
Inspection Before Shipment
For custom threaded components, dimensional accuracy is only part of the inspection.
Our inspection process can focus on:
Dimensional Inspection
- · Overall dimensions
- · Outer diameter
- · Bore diameter
- · Flange dimensions
- · Thread dimensions
Functional Inspection
- · Thread engagement
- · Mating fit
- · Bore clearance
- · Assembly interface
Visual Inspection
- · Burrs
- · Scratches
- · Surface defects
- · Machining marks
- · Edge condition
For tighter requirements, inspection methods can be specified according to the customer's drawing and quality requirements.
