S-90605A303 M10 x 25 mm DIN 912, ISO 4762 Left-Hand Threaded Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 170,000 psi ensures reliable performance under high-stress conditions, reducing the risk of fastener failure in critical applications.
• Superior hardness (Rockwell C37) provides excellent wear resistance and durability, extending the service life of components in demanding environments.
• Black-oxide coating on alloy steel offers enhanced corrosion resistance, protecting against rust and maintaining appearance in various industrial settings.
• Left-hand thread design prevents unintentional loosening in rotating machinery, providing secure fastening where standard right-hand threads may fail.
• 8mm hex socket drive allows for high torque application with standard tools, ensuring tight installation and easy maintenance access in confined spaces.
• Class 12.9 strength rating guarantees consistent mechanical properties, delivering predictable performance for precision engineering applications.
• Full thread coverage along the 25mm length provides maximum grip and load distribution, improving joint integrity across the entire fastened area.

Professional Applications & Engineering Value

These M10 socket head cap screws with left-hand thread metric configuration solve critical reverse-rotation challenges in industrial machinery, conveyor systems, and rotating equipment where standard threads would naturally loosen. The black-oxide alloy steel construction combined with Class 12.9 strength provides exceptional resistance to vibration-induced fatigue and environmental corrosion, making them ideal for automotive assemblies, heavy equipment manufacturing, and precision tooling applications. The coarse thread pitch (1.5mm) ensures quick installation and reliable performance in materials where fine threads might strip, while the 8mm hex drive socket head design accommodates high torque requirements without compromising tool access in space-constrained installations.

Specification Summary & Compliance

This fully threaded socket head cap screw maintains precise Class 5g6g thread fit tolerance per metric standards, ensuring consistent engagement and load distribution. Manufacturing complies with DIN 912/ISO 4762 specifications for dimensional accuracy and mechanical properties. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulatory requirements, confirming environmental compliance for industrial applications worldwide.
