Custom 304 Stainless Steel Precision Threaded Shaft with Step Shoulder & Milled Flat Swiss CNC Turned Threaded Shaft

Product Description

This custom stainless steel threaded shaft is produced on Swiss type CNC lathes with one-time clamping to guarantee high coaxiality and dimensional consistency. The part integrates step shoulders, continuous thread and milled flat feature. Raw material is 304 stainless steel, finished with deburring and bright polishing without plating coating.

We are an experienced manufacturer providing custom service and OEM machining for various precision threaded shafts, threaded studs and threaded pins. We can adjust thread specification, shoulder size, flat position, total length and material grade strictly following your technical drawings or physical samples for different automation and equipment assemblies.

Technical Specifications

Applications

• Automation equipment assembly
• Medical instrument components
• Optical equipment fixtures
• Electronic test jigs & fixtures
• Packaging machinery parts
• Laboratory instrument fittings
• Transmission adjustment mechanism

Custom & OEM Service

We provide full custom and OEM service for precision threaded shaft products. You can send us 2D/3D CAD drawings or physical samples. We support customization on material, thread standard, thread pitch, shoulder dimension, milled flat size, total length, tolerance requirement and surface finish. Our engineering team will review your design and provide technical suggestion and quotation quickly. Small batch and mass production are both acceptable.

Key Advantages

• Single clamping Swiss CNC machining avoids secondary clamping error, solves poor concentricity issue of multi-process machined shafts
• Tight controllable tolerance meets high-precision assembly requirement, eliminates fitting gap and stuck problem
• Natural polished 304 stainless steel surface, anti-rust, no coating peeling risk for clean environment use
• Flexible custom service, we modify structure and specs as your design instead of only supplying standard off-the-shelf parts
• Stable batch consistency, reduce part difference which causes unstable equipment running

Quality Control

• Raw material incoming inspection: material certification verification for stainless steel
• First article inspection before mass production
• In-process dimension checking with micrometer, thread gauge, optical comparator
• Full visual inspection for burr, scratch and surface defect
• Final outgoing dimension inspection and quality report available on request

Shipping & Delivery

• Sample lead time: 3-7 working days after drawing confirmation
• Mass production lead time: 7-15 working days, depends on order quantity and complexity
• Shipping options: DHL, FedEx, UPS, TNT, sea freight, air freight
• Packaging: Anti-rust oil + plastic tube + carton packaging for precision shaft protection
