S-91502A101 M3 x 5 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 170,000 PSI ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
• Superior corrosion resistance from blue-dyed zinc plating protects against environmental damage, extending service life in harsh conditions.
• Precise Class 5g6g thread fit provides consistent engagement and vibration resistance, minimizing loosening in dynamic assemblies.
• High Rockwell C37 hardness offers excellent wear resistance, maintaining thread integrity through repeated use and installation.
• Standard 2.5mm hex drive allows for easy installation with common tools, reducing assembly time and improving workflow efficiency.
• Fully threaded M3 coarse pitch design ensures maximum holding power and faster installation across various material thicknesses.
• Compliance with international standards including DIN 912/ISO 4762 guarantees interchangeability and quality consistency in global projects.

Professional Applications & Engineering Value

These M3 socket head cap screws deliver critical engineering value in applications where space constraints and high clamping forces coexist. The Class 12.9 alloy steel construction provides exceptional strength-to-weight ratio, solving common challenges in industrial machinery, automotive assemblies, and precision equipment where vibration resistance and reliability are paramount. The blue-dyed zinc-plated surface treatment not only offers corrosion protection but also allows for visual identification in complex assemblies. With fully threaded coarse pitch design, these fasteners ensure maximum thread engagement in both soft and hard materials, while the standard hex drive accommodates high torque applications without stripping. This combination addresses key industrial pain points including fastener fatigue, corrosion-induced failure, and installation efficiency in high-volume production environments.

Specification Summary & Compliance

Manufactured to precise Class 5g6g thread fit tolerances per metric standards, these screws maintain dimensional accuracy for consistent performance. The product strictly adheres to DIN 912/ISO 4762 manufacturing specifications for socket head cap screws, ensuring proper head profile and drive compatibility. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and regulatory acceptance for international industrial applications, while the documented 170,000 PSI tensile strength and Rockwell C37 hardness provide verified mechanical performance data for engineering calculations.
