Stainless Steel Hex Stud with Internal & External Threads
We specialize in CNC machining of stainless steel hex studs with both internal and external threads, focusing on secure connections, precise threading, and strong adaptability. These components are widely used in precision machinery, industrial equipment, instrumentation, and tooling fixtures.
With factory-direct supply, we support global low-volume, multi-variety customization of 304 stainless steel turned parts. Featuring precision dual-thread machining and standardized surface treatments, our products are ideal for stepped or dual-diameter connections, making them essential components for high-precision industrial assemblies.
Available materials include 303, 304, and 316 stainless steel. Our factory operates 24/7 with a wide range of turning equipment, allowing us to meet different precision and cost requirements. Sample delivery can be completed within 7–10 hours, and small-batch orders can be delivered within 3–5 days.
We provide full customization with fast response:
• Hex size (across flats)
• Overall length
• Internal and external thread specifications (metric, imperial, unified, fine thread, custom)
• Internal thread depth
• External thread length
• Custom combinations of internal/external thread sizes
Our engineers offer one-to-one drawing evaluation, with quotations provided within 12 hours. Flexible production scheduling and direct factory supply ensure efficient and precise solutions for various connection applications.
Material & Process Advantages
We use high-quality stainless steel combined with standardized surface treatments such as passivation, zinc plating, zinc-nickel alloy plating, and chrome plating.
Key Benefits
• Excellent machinability for precise turning and threading of both internal and external threads.
• Thread accuracy meets international 6H standards, with smooth, burr-free profiles ensuring easy assembly without jamming.
• Strong and stable connections with minimal risk of loosening.
• Precisely machined hex head with uniform across-flat dimensions for secure tool engagement without slipping or edge damage.
• Multiple surface treatment options:
☉ Passivation for base corrosion protection.
☉ Zinc, zinc-nickel, and chrome plating for enhanced wear and corrosion resistance.
• Suitable for indoor, outdoor, high-humidity, and workshop environments.
• High structural strength ensures resistance to deformation, cracking, or thread stripping under load.
• Reinforced integrity at the interface between internal and external threads for long-term durability.
These advantages make our 304 stainless steel turned parts highly reliable for precision connection applications.
Precision Manufacturing
Optimized Dual-Thread Machining
To ensure high coaxiality between internal and external threads, machining processes are optimized using one-piece forming and dedicated tapping tools. Coaxiality is controlled within ≤0.02 mm, with thread standards meeting 6G class requirements.
Strict Precision Standards
• Across flats tolerance: ±0.03 mm
• Overall length tolerance: ±0.03 mm
• Thread accuracy compliant with international standards
• Geometric tolerance: ≤0.03 mm
Full Quality Control System
• Raw material composition inspection
• Hex material verification
• First article inspection
• Full dimensional inspection
• Thread Go/No-Go gauge testing
• Surface treatment quality inspection
• Thread fit and assembly testing
Each process is 100% inspected, ensuring consistent quality and zero defects.
• Packaging: PE bag + carton, with custom packaging available
• Individual anti-scratch protection + outer carton with impact cushioning
• Compliant with international shipping standards
• Lead time:
☉ 7–10 days for small batches
☉ 15–30 days for mass production
We provide dedicated one-to-one service for global buyers of 304 stainless steel turned parts.
