S-91760A423 M8 x 16 mm DIN 912, ISO 4762 Alloy Steel Thread-Locking Socket Head Screws

Key Features & Benefits at a Glance

• Secure vibration-resistant locking with integrated nylon patch thread locker that maintains integrity across a wide temperature range from -70° to 250°F
• Exceptional tensile strength of 170,000 psi ensures reliable performance in high-stress industrial applications
• Superior corrosion resistance thanks to the black-oxide finish on alloy steel, extending service life in demanding environments
• Precise thread engagement with Class 5g6g thread fit and coarse 1.25mm pitch for quick assembly and reliable fastening
• Optimal torque transmission through the standard hex socket head design, preventing stripping and enabling high clamping forces
• Full thread coverage along the entire 16mm length provides maximum grip and load distribution across joined components
• Industry-standard compatibility meeting DIN 912/ISO 4762 specifications for seamless integration into existing metric fastener systems

Professional Applications & Engineering Value

These M8 socket head cap screws deliver critical engineering solutions where vibration resistance and mechanical integrity are paramount. The black-oxide alloy steel construction combined with Rockwell C37 hardness provides exceptional durability against wear and environmental exposure, making them ideal for machinery, automotive assemblies, and industrial equipment subjected to dynamic loads. The integrated nylon patch thread locker eliminates the need for separate locking washers or adhesives, streamlining assembly while preventing loosening from vibration - a common failure point in rotating equipment and mobile applications. The fully threaded design with coarse metric thread pitch ensures rapid installation and maximum thread engagement, while the hex socket drive accommodates high torque applications in confined spaces where wrench clearance is limited.

Specification Summary & Compliance
