Key Features and Technical Specifications

Optimized Load Distribution

The radially curved bearing surface of these screws minimizes point loading on soft substrates such as composites and cast alloys. This design reduces the risk of material deformation, ensuring a secure and stable connection even in delicate applications. The head height tolerance of ±0.20mm (e.g., M6: 4.0mm vs. DIN 912’s 6.0mm) further enhances their adaptability to specific engineering requirements.

High-Torque Drive System

These screws feature an extended socket depth of ≥1.5× nominal diameter (per DIN 7991:2014 Sec. 4.3), ensuring compatibility with high-torque tools. The ISO 10664 Class C drive conformity (±0.028mm tolerance) guarantees precise alignment and reduces the likelihood of tool slippage during installation.

Performance-Graded Materials

Available in 12.9/10.9/8.8 strength classes, these screws are manufactured using SCM435 alloy steel, offering exceptional tensile strength and durability. Corrosion resistance is further enhanced with black oxide (≥96h salt spray) or Geomet® coating (≥720h), making them suitable for harsh environments.

Key Applications

Aerospace

In aerospace engineering, the reduced head height of these screws contributes to weight savings in turbine assemblies, a critical factor in optimizing fuel efficiency and performance. The radially curved bearing surface ensures even load distribution on composite materials, minimizing the risk of structural failure under extreme conditions.

Automotive

For automotive applications, the curved head design prevents thread galling in aluminum engine blocks, a common issue in high-torque environments. This feature is particularly valuable in modern vehicles where lightweight materials are increasingly used to meet emissions standards.

Medical

The passivated stainless steel construction of these screws meets ISO 13485 biocompatibility standards, making them ideal for medical devices and surgical instruments. Their corrosion resistance and precision make them suitable for implantable devices and sterilization processes.

Precision Engineering

The head-to-shank transition radius of ≥0.1d (vs. DIN’s ≥0.08d) reduces stress concentration, enhancing fatigue resistance in precision machinery. This design is crucial for applications requiring long-term reliability, such as CNC equipment and robotics.
