S-91290A456 M8 x 60 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional Tensile Strength - With 170,000 psi tensile strength, this screw withstands extreme loads and vibrations, reducing the risk of failure in high-stress applications.
• Superior Corrosion Resistance - The black-oxide coating on alloy steel provides enhanced protection against rust and environmental degradation, extending service life in harsh conditions.
• Precision Thread Fit - Class 5g6g thread fit ensures smooth, reliable engagement with mating parts, minimizing play and improving assembly accuracy.
• Optimized Drive Efficiency - The 6mm hex socket drive allows for high torque application with standard tools, preventing stripping and enabling quick, secure installations.
• High Hardness Durability - Rockwell C37 hardness offers excellent wear resistance, maintaining thread integrity and fastener performance over repeated use.
• Versatile Partially Threaded Design - 28mm minimum thread length provides flexibility for clamping unthreaded sections while ensuring strong threaded engagement where needed.
• Global Standard Compliance - Manufactured to DIN 912/ISO 4762 specifications, guaranteeing dimensional accuracy and interchangeability in international projects.

Professional Applications & Engineering Value

This M8 socket head cap screw delivers critical engineering value in demanding industrial environments where reliability is non-negotiable. The black-oxide alloy steel construction combined with Class 12.9 strength rating makes it ideal for heavy machinery, automotive assemblies, and precision equipment subjected to dynamic loads and vibration. The partially threaded metric design allows engineers to securely fasten components while minimizing thread damage in non-critical sections. With its coarse 1.25mm pitch threads and right-hand thread direction, this fastener provides rapid installation and superior resistance to loosening in high-vibration applications. The standard socket head profile with 6mm hex drive ensures compatibility with common tools while accommodating space-constrained designs where wrench clearance is limited.

Specification Summary & Compliance

This socket head cap screw features precision Class 5g6g thread fit per ISO metric standards, ensuring consistent performance across mating components. Manufacturing strictly adheres to DIN 912/ISO 4762 specifications for dimensional accuracy, including 13mm head diameter, 8mm head height, and 60mm total length. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, containing no restricted substances and meeting the latest environmental standards for industrial applications worldwide.
