S-91760A426 M8 x 20 mm DIN 912, ISO 4762 Alloy Steel Thread-Locking Socket Head Screws

Key Features & Benefits at a Glance

• Vibration-resistant locking with nylon patch thread locker that maintains secure fastening even under dynamic loads and temperature fluctuations from -70° to 250°F
• Exceptional strength-to-weight ratio from alloy steel construction with 170,000 psi tensile strength for demanding industrial applications
• Precise torque transmission through 6mm hex drive socket head design that prevents tool slippage and ensures consistent installation
• Corrosion-resistant black-oxide finish that provides durable protection while maintaining dimensional accuracy
• Reliable thread engagement with Class 5g6g thread fit and coarse 1.25mm pitch for quick assembly and reduced cross-threading risk
• Full thread coverage along the entire 20mm length for maximum grip and load distribution in various material thicknesses
• Global compliance assurance meeting DIN 912/ISO 4762 standards plus RoHS 3 and REACH environmental regulations

Professional Applications & Engineering Value

These M8 socket head cap screws with nylon patch thread locker solve critical vibration-induced loosening problems in machinery, automotive, and industrial equipment applications. The black-oxide alloy steel construction provides superior corrosion resistance while maintaining the Rockwell C37 hardness needed for repeated disassembly and reassembly cycles. The fully threaded M8 x 1.25mm coarse thread design ensures maximum engagement in both thick and thin materials, while the hex drive socket head allows for high-torque installation in confined spaces. Engineered to DIN 912/ISO 4762 specifications, these metric socket head screws deliver reliable performance in temperature-sensitive environments from -70° to 250°F, making them ideal for precision equipment, manufacturing fixtures, and automotive assemblies where vibration resistance and dimensional stability are paramount.
