S-93705A819 M3 x 25 mm DIN 912, ISO 4762 18-8 Stainless Steel Thread-Locking Socket Head Screws

Key Features & Benefits at a Glance

• Vibration-resistant locking: Integrated nylon patch thread locker ensures reliable, permanent fastening that withstands loosening under dynamic loads and thermal cycling from -70° to 250°F.
• Superior corrosion resistance: Made from 18-8 stainless steel, offering excellent durability and rust resistance in harsh industrial environments.
• High-strength performance: With a 70,000 psi tensile strength, this screw provides robust clamping force for demanding applications.
• Secure and precise installation: The hex socket drive (2.5 mm) allows for high torque application and prevents cam-out, ensuring tight, flush fastening.
• Optimized thread engagement: Partially threaded design with 18 mm minimum thread length concentrates clamping force where needed, improving joint integrity.
• Interchangeable and standardized: Conforms to DIN 912 / ISO 4762 specifications, ensuring compatibility with global metric assembly systems.
• Consistent quality and fit: Class 6g thread fit with coarse M3 x 0.5 mm pitch guarantees easy assembly and reliable performance in high-volume production.

Professional Applications & Engineering Value

This M3 socket head cap screw is engineered to solve critical fastening challenges in precision assemblies. The 18-8 stainless steel construction resists oxidation and chemical exposure, making it ideal for electronics enclosures, machinery frames, and outdoor equipment. The permanent nylon patch thread locker eliminates the need for separate locking hardware, reducing assembly time and preventing failures in vibrating environments like automotive subsystems or conveyor systems. Its partial threading ensures that the unthreaded shank bears shear loads effectively, while the hex socket drive provides a clean, low-profile finish. Complying with DIN 912 / ISO 4762, it delivers reliable performance in automated or manual installations, supporting efficient production lines and maintenance operations.

Specification Summary & Compliance

This screw features a Class 6g thread fit with M3 x 0.5 mm coarse metric threading, ensuring dimensional accuracy per DIN 912 / ISO 4762 standards. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming its suitability for regulated industrial and consumer applications without hazardous substances.
