S-98093A320 M5 x 20 mm ISO 898-1, DIN 6921 High-Strength Metric Class 10.9 Steel Flanged Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional durability with Class 10.9 high-strength steel, ensuring reliable performance under heavy loads and high-stress conditions.
• Superior corrosion resistance from the black-phosphate coating, extending service life in harsh industrial environments.
• Enhanced grip and stability with the integrated flange, distributing load evenly and preventing loosening in vibrating applications.
• Precise and secure fastening thanks to the M5 coarse thread (0.8mm pitch) and Class 6g fit, enabling quick installation and robust connections.
• Optimized for high-torque applications with an external hex drive and 8mm head width, allowing for easy tightening with standard tools.
• Full threading for maximum holding power along the entire 20mm length, providing consistent clamping force across the joint.
• Compliance with international standards including DIN 6921 and ISO 898-1, ensuring consistent quality and interchangeability.

Professional Applications & Engineering Value

Engineered for demanding industrial settings, these M5 hex head screws deliver outstanding mechanical properties with a tensile strength of 150,000 psi and Rockwell C32 hardness, making them ideal for heavy machinery, automotive assemblies, and structural frameworks. The black-phosphate steel finish provides a robust barrier against rust and chemical exposure, significantly reducing maintenance needs in corrosive environments. Featuring a flanged design, they eliminate the need for separate washers, speeding up assembly while enhancing vibration resistance. With fully threaded coarse metric threads, these screws ensure rapid installation and reliable performance in high-vibration applications, supporting efficient production lines and long-term operational safety.
