Custom CNC Turned Stainless Steel Threaded Ball Studs
Drawing-based components for OEM assemblies, prototypes, and repeat production.
This component appears to be a polished stainless steel ball-ended threaded stud manufactured by CNC turning. Its visible structure combines a spherical head, a cylindrical transition section, a shoulder or locating step, and an external threaded shank. The exact material grade, thread standard, dimensions, and tolerance requirements are subject to drawing review.
Shenzhen Perfect Precision Products Co., Ltd. provides drawing-based CNC machining for metal components, with CNC turning, mill-turn machining, material and process review, dimensional inspection, and finishing coordination for project-dependent requirements.
Why buyers specify this type of component
ⓘ Send the 2D drawing or 3D model with the thread call-out and required quantity. The engineering team can review manufacturability and prepare a quotation based on the defined scope.

Product-Specific Selling Points
1. Designed around the mating thread
A ball stud can look simple while still creating assembly problems if the thread size or pitch is wrong. Submit the mating requirement for review.
2. Functional Spherical Head Geometry
The ball surface may be used for contact or adjustment. Diameter, roundness, and surface condition will be quoted and inspected according to the drawing.
3. Project-Specific Material Selection
Grade selection follows the environment and strength requirement. Material certification can be requested when required.
Manufacturing Process and Quality Control
Drawing and manufacturability review
Engineering team reviews ball diameter, thread standard, and critical tolerances.
Material verification
Buyer specifies the stainless steel grade; mill test certification can be requested.
CNC turning & Finishing
Rotational geometry machined, followed by specified polishing or passivation.
Dimensional inspection
CMM and 2D measuring instruments verify critical dimensions before shipment.
Customization and RFQ Requirements
For an accurate quotation, please provide:
- 2D engineering drawing and 3D CAD file.
- Stainless steel grade and material condition.
- Thread standard, nominal size, and pitch/TPI.
- Critical tolerances and surface finish requirements.
- Required quantity and target delivery date.
Frequently Asked Questions
Can you manufacture the external thread to a specific standard?
Yes. The thread can be reviewed against the buyer’s drawing. Please specify metric or inch system, size, and pitch.
What tolerance can you achieve?
Standard machining tolerance of ±0.01 mm, and ±0.005 mm for special precision areas depending on geometry.
