Custom Stainless Steel Threaded Bushing - Precision CNC Turned

Custom Stainless Steel Threaded Bushing - Precision CNC Turned

A small, strong sleeve made from stainless steel with neat internal or external threads. Made by CNC turning to tight tolerances for a smooth fit, long life, and good corrosion resistance. Available in custom sizes, thread types, and surface finishes for tough or clean environments.

Usage scenarios:
- Joining pipes, tubes, or panels where a durable threaded adapter or spacer is needed in marine, HVAC, or plumbing systems.
- As a precision insert for machinery, tools, or fixtures to align shafts, protect threads, or convert thread sizes in automotive and industrial equipment.
- In electronic housings, medical devices, and outdoor fittings where corrosion resistance and exact fit are required.

Product features

Custom stainless steel threaded bushings use a stepped body with an external thread larger than the internal thread to join pipes of different sizes, functioning as reducers that deliver secure, leak‑resistant connections with corrosion-resistant mechanical strength. Backed by ISO 9001:2015 certification and OEM/ODM services, these components are manufactured as precision cnc turned parts using CNC Swiss, turning and milling plus centerless grinding to achieve tight tolerances, repeatable quality, and cost-effective scalability. The product’s threaded geometry, accurate shoulder interfaces and high surface finish provide reliable alignment, load transfer and easy assembly for demanding applications across 5G, aerospace, medical and energy industries.

Product Introduction

Stainless Steel Screwed Bushings are the pipe fittings in which the external thread is larger than its internal thread. This allows two pipes of different sizes to be connected. It can be used to reduce the threaded fittings.

Frequently Asked Questions about

What's the difference between a lathe, a screw machine, a truning center, and a CNC lathe?

In its simplest form, a lathe is a machine that can make turned parts from bar stock, but has no milling capability. Screw machines, turning centers, and CNC lathes are lathes that have the ability to turn and mill parts. Turning centers and Swiss lathes can typically make more complicated parts than screw machines, and are better-suited for parts with tight engineering tolerances. Swiss lathes tend to be better for small, thin, and long parts than screw machines and turning centers.

What type of parts does MaiJin Metal service make? What services do you offer?

We manufacture custom metal and plastic parts from bar or tube stock to the highest standards of quality and precision. We provide CNC Swiss machining, CNC turning and milling, and two types of centerless grinding.

What information do you need to quote my part?

In order to provide a meaningful quote, we only require the following information: A fully dimensioned print, drawing, sketch in either PDF or CAD format All required raw materials Any necessary secondary operations, including heat treating, plating, or finishing specifications Any applicable customer specifications, such as First Article Inspection, PPAP requirements, and required outside process certificates Expected quantity or quantities Any other useful information, such as target pricing

What industries do you serve?

We are involved with almost every industry imaginable. We serve 5G, AI, aerospace, energy, medical, dental, and many others.

What is the smallest part you can make? What is the largest part you can make?

The short answer is “it depends.” Things like your needs, part complexity, the type of manufacturing, and many other factors are at play. In general, we can machine parts with minor outside diameters (ODs) as small as 2mm (0.080”) and major ODs as large as 200mm (8”). If you’re looking for help nailing down those factors, we encourage you to contact our technical sales staff early in the design cycle so we can review your part and provide insight and assistance.

we welcome custom designs and ideas and is able to cater to the specific requirements. for more information, please visit the website or contact us directly with questions or inquiries.
