S-90304A322 M2 x 4 mm ISO 7045 Steel Pan Head Torx Screws

Key Features & Benefits at a Glance

• Enhanced Corrosion Resistance: Zinc-plated steel construction provides reliable protection against rust and environmental degradation, extending service life in demanding industrial settings.
• Superior Torque Transmission: T6 Torx drive design minimizes cam-out risk, allowing for higher torque application and reducing tool wear and fastener head damage.
• High Tensile Strength: With a 60,000 psi tensile strength and Rockwell B71 hardness, this screw delivers exceptional clamping force and resistance to shear and tensile loads.
• Precision Thread Fit: Class 6g thread fit ensures consistent, secure engagement with mating parts, reducing the risk of loosening under vibration and dynamic stresses.
• Broad Compatibility: Fully threaded M2 x 0.4mm coarse thread design offers versatile fastening for a wide range of materials and assembly applications.
• Streamlined Assembly: The low-profile pan head design provides a flush or slightly raised finish, ideal for applications where clearance is a concern.
• Regulatory Assurance: Compliance with ISO 7045, RoHS 3, and REACH ensures material safety and performance reliability for global supply chain requirements.

Professional Applications & Engineering Value

This M2 x 0.4mm zinc-plated steel Torx pan head screw is engineered to address critical fastening challenges in precision assemblies, such as electronics, automotive components, and small machinery. The zinc-plated steel material offers a cost-effective balance of strength and corrosion resistance, essential for longevity in varied operational environments. The Torx T6 drive significantly reduces the risk of stripping during high-torque installation, a common issue in automated or repetitive assembly lines, thereby minimizing production downtime. Its fully threaded design with a Class 6g fit ensures uniform load distribution and vibration resistance, making it ideal for securing sensitive parts where loosening could lead to failure. By meeting ISO 7045 standards, it guarantees dimensional consistency and interoperability, supporting efficient manufacturing and maintenance processes.
