17-4PH Stainless Steel Parallel Key
Product Overview
17-4PH stainless steel parallel key is a precision-machined mechanical component used extensively in the transmission systems of machines and equipment. Designed to transmit torque between shafts and rotating components such as gears, pulleys, and couplings, parallel keys offer effective anti-rotation performance. The 17-4PH stainless steel alloy adds superior strength, hardness, and corrosion resistance to the parallel key, making it suitable for high-performance and harsh industrial environments.
Flybear Fastener designs and manufactures premium 17-4PH stainless steel parallel keys that meet international standards with exceptional dimensional accuracy and mechanical stability.

Material Introduction & Production Process
17-4PH is a martensitic stainless steel known for combining high strength and excellent corrosion resistance. It offers superior mechanical properties compared to 304 or 316 stainless steel, particularly after precipitation hardening.
Advantages of 17-4PH Stainless Steel:
- High tensile and yield strength
- Excellent corrosion resistance in chloride-containing environments
- Good machinability and weldability
Production Workflow:
Raw Material → Precision Cold Forming → CNC Milling / Cutting → Heat Treatment (Aging) → Surface Grinding → Inspection → Packaging
Flybear Fastener ensures precise control at each stage to deliver dimensionally accurate and high-strength parallel keys that meet the exacting standards of modern engineering applications.
Typical Applications and Industries
The 17-4PH stainless steel parallel key is commonly found in:
- Aerospace components
- Marine and offshore machinery
- Industrial gearboxes
- Food processing equipment
- Wind and hydro turbines
- High-performance automotive systems
- Military and defense applications
These scenarios demand high fatigue strength and corrosion resistance, which our parallel key delivers consistently.
Product Advantages & Competitive Edge
Superior Material:
We use certified 17-4PH SS material that offers greater mechanical strength and stress tolerance than common carbon steels or lower-grade stainless variants.
Precision Manufacturing:
Tightest tolerances are maintained through CNC machining and grinding, ensuring perfect shaft-hub fit.
Advanced Surface Treatment:
The brushed or ground finish ensures better fit and smoother installation, reducing wear and assembly issues.
Strong Customization Capability:
Available in multiple sizes or made-to-order based on customer-provided CAD or physical samples.
Reliable Inventory & Fast Shipping:
With sufficient stock and robust warehousing capability, Flybear Fastener ensures fast order dispatch on both standard and custom products.
Outstanding After-Sales Service:
We also provide timely technical support, specification selection consultation, and warranty-backed products.
Inspection & Quality Control
Quality is the cornerstone at Flybear Fastener. Our stringent inspection processes include:
- Dimensional inspection with digital calipers and CMM
- Surface hardness test post heat treatment
- Salt spray testing (ASTM B117) for corrosion resistance
- Optical sorting and thread inspection where applicable
- Tensile test and fatigue test reports available upon request
We adhere to ISO 9001 and IATF16949 certified quality management systems, ensuring every piece we ship meets both functional and regulatory requirements.
Selection & Procurement Guide
Here are a few tips to select the right 17-4PH stainless steel parallel key for your application:
- Confirm the key slot dimensions on both shaft and hub.
- Ensure compatibility with the applicable DIN, ISO, or ANSI specification.
- Select appropriate length and width tolerances based on torque needs.
- For harsh environments, prioritize high corrosion resistance (i.e., choose only 17-4PH or similar grade).
- In high-volume applications, opt for custom solutions for better cost-performance.
Custom lengths, chamfered ends, and pre-installed options can significantly simplify your assembly process and improve project timelines.
