S-91290A302 M2.5 x 15 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Maximum load-bearing capacity with Class 12.9 rating and 170,000 PSI tensile strength for critical high-stress applications
• Enhanced corrosion resistance through black-oxide surface treatment on alloy steel, extending service life in demanding environments
• Superior thread engagement with Class 4g6g thread fit and coarse pitch (0.45mm) for faster assembly and reduced cross-threading risks
• Precise torque transmission via 2mm hex drive and standard socket head profile, minimizing tool slippage and head stripping
• Exceptional hardness durability with Rockwell C37 rating, maintaining fastener integrity under repeated loading cycles
• Full thread coverage along the 15mm length ensures consistent clamping force distribution across the entire engagement area
• Global compliance assurance meeting DIN 912/ISO 4762 manufacturing standards alongside RoHS 3 and REACH environmental regulations

Professional Applications & Engineering Value

This M2.5 socket head cap screw delivers critical performance where space constraints meet high mechanical demands. The black-oxide alloy steel construction provides essential corrosion protection while maintaining the Class 12.9 strength rating needed for structural applications. Engineers specify these metric socket screws for precision machinery, automotive assemblies, and industrial equipment where the combination of 4.5mm head diameter and 2mm hex drive enables compact designs without sacrificing installation torque. The coarse thread pitch (0.45mm) ensures rapid assembly in production environments while the fully threaded design guarantees uniform stress distribution. These DIN 912/ISO 4762 compliant fasteners solve vibration-induced loosening problems in dynamic applications through optimized thread engagement and material hardness.

Specification Summary & Compliance

Manufactured to DIN 912/ISO 4762 specifications with Class 4g6g thread fit tolerance ensuring precise dimensional accuracy. The metric coarse thread (M2.5 x 0.45mm) follows standardized spacing for compatibility with industry components. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental responsibility. The 15mm length maintains strict dimensional control per international fastener standards for reliable interchangeability in global supply chains.
