S-91290A020 M1.6 x 3 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, preventing fastener failure.
• Superior corrosion resistance from the black-oxide finish extends service life in harsh or humid industrial environments.
• High hardness rating (Rockwell C37) provides excellent wear resistance, maintaining thread integrity through repeated use.
• Precision Class 5g6g thread fit guarantees smooth installation and secure fastening with minimal risk of cross-threading.
• Compact 1.5mm hex drive design allows for easy installation in confined spaces with standard tools.
• Fully threaded shank offers consistent clamping force along the entire length for uniform load distribution.
• Compliance with international standards including DIN 912/ISO 4762 ensures interchangeability and quality consistency.

Professional Applications & Engineering Value

These M1.6 socket head cap screws deliver critical engineering value in precision assemblies where space constraints and performance reliability are paramount. Manufactured from Class 12.9 alloy steel with black-oxide surface treatment, they solve common industrial challenges like corrosion-induced degradation and vibrational loosening in compact machinery, electronic enclosures, and automotive components. The coarse thread pitch (0.35mm) combined with right-hand threading ensures rapid installation and high resistance to back-out under dynamic loads. Their fully threaded metric design provides superior grip in thin materials, making them ideal for applications demanding both high tensile strength and dimensional precision in challenging environments.

Specification Summary & Compliance

This socket head cap screw features M1.6x0.35mm coarse threads with Class 5g6g tolerance per ISO metric standards, ensuring precise fit. Manufacturing conforms to DIN 912 / ISO 4762 specifications for dimensional accuracy and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and regulatory adherence for global industrial use.
