Material Introduction and Production Process
The Carbon Steel Parallel Key DIN6885 is typically manufactured using high-strength carbon steel grades such as C45 or C40, known for their excellent tensile strength and wear resistance. These materials offer a balanced combination of machinability and mechanical performance, making them ideal for torque transmission systems.
The standard production process includes:
Raw Material Selection → Cold Drawing → Cutting → Precision Machining (Milling/Grinding) → Heat Treatment → Surface Treatment → Final Quality Inspection → Packaging.
Heat treatment increases hardness and fatigue resistance, while surface treatments enhance resistance to corrosion and improve performance in harsh working environments.
Applications Across Industries and Environments
The Carbon Steel Parallel Key DIN6885 is widely utilized in several key industries including:
- Automotive transmissions and drivetrains
 - Agricultural machinery and harvesters
 - Industrial gearboxes and conveyors
 - Marine applications and propeller connections
 - Electric motors and pump assemblies
 - Wind turbine mechanical locking systems
 
These keys play a vital role in ensuring secure coupling by preventing slippage between shafts and mounted components.

Selection and Procurement Guide
When selecting a Carbon Steel Parallel Key DIN6885, it’s essential to verify compatibility with shaft and hub tolerances. Key dimensions (width, height, and length) should match shaft keyways to avoid excess movement. Surface treatments must be chosen based on the operational environment (e.g., zinc-plated for moist environments, black oxide for indoor machinery).
Ensure you check for standard compliance (DIN/ISO) to maintain consistency across replacement parts and assemblies.
For non-standard sizes or unique applications, Flybear Fastener provides custom machining services with fast prototype delivery for R&D and production testing.
