S-91502A114 M3 x 50 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 the blue-dyed zinc plating protects against rust and extends service life in harsh industrial environments.
• Precise Class 5g6g thread fit provides smooth assembly and secure fastening, minimizing play and vibration loosening.
• High hardness (Rockwell C37) offers excellent wear resistance, maintaining thread integrity through repeated use.
• Partially threaded design allows for controlled clamping force and easier alignment in precision assemblies.
• Standard hex drive (2.5 mm) enables efficient installation with common tools, speeding up production and maintenance tasks.
• Compliance with DIN 912/ISO 4762 guarantees dimensional accuracy and interchangeability, ensuring consistent quality across global projects.

Professional Applications & Engineering Value

These M3 socket head cap screws are engineered from alloy steel to address critical challenges in industrial settings, such as vibration-induced loosening and material fatigue. The Class 12.9 strength rating and metric coarse thread (0.5 mm pitch) provide robust clamping force for machinery, automotive components, and precision equipment, where reliability is paramount. The blue-dyed zinc-plated finish not only enhances corrosion resistance but also allows for easy visual identification in complex assemblies. With a partially threaded rod and right-hand thread direction, these screws facilitate quick alignment and secure fastening in tight spaces, reducing installation time and improving overall structural integrity in demanding applications.

Specification Summary & Compliance

This socket head cap screw features an M3 x 0.5 mm thread with a Class 5g6g thread fit per ISO standards, ensuring precise tolerance for consistent performance. It adheres to DIN 912/ISO 4762 manufacturing specifications for dimensional accuracy and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious and regulated industries.
