S-91760A248 M5 x 25 mm DIN 912, ISO 4762 Alloy Steel Thread-Locking Socket Head Screws

Key Features & Benefits at a Glance

• Vibration-resistant locking: Permanent Nylon patch thread locker prevents loosening under dynamic loads, ensuring long-term assembly integrity.
• Exceptional corrosion protection: Black-oxide finish on alloy steel provides superior resistance to rust and environmental degradation.
• High-strength performance: 170,000 psi tensile strength and Rockwell C37 hardness withstand extreme mechanical stresses.
• Wide temperature tolerance: Reliable operation from -70° to 250° F (-57° to 121° C) for diverse industrial environments.
• Precision metric threading: Class 5g6g coarse thread (M5 x 0.8 mm) ensures smooth installation and secure fastening.
• Standardized dimensions: DIN 912/ISO 4762 compliance guarantees interchangeability and consistent quality.
• Secure hex drive: 4 mm socket drive provides positive torque transmission and prevents tool slippage.

Professional Applications & Engineering Value

These M5 socket head cap screws with Nylon patch thread locking technology solve critical vibration-induced loosening problems in industrial machinery, automotive assemblies, and precision equipment. The black-oxide alloy steel construction delivers enhanced corrosion resistance where environmental exposure is a concern, while the fully threaded design and coarse thread pitch enable rapid installation and maximum thread engagement in various materials. With 170,000 psi tensile strength and maintained performance across extreme temperatures (-70° to 250° F), these metric screws provide reliable fastening solutions for high-stress applications where disassembly is not anticipated, reducing maintenance costs and improving operational safety.
