S-91502A110 M3 x 25 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional Durability: Class 12.9 alloy steel construction provides superior resistance to wear and fatigue, extending service life in high-stress environments.
• High Tensile Strength: With a tensile strength of 170,000 psi, these screws reliably withstand heavy loads and prevent fastener failure.
• Enhanced Corrosion Resistance: Blue-dyed zinc plating offers a protective barrier against rust and environmental degradation, ideal for various industrial settings.
• Precise Hex Drive Engagement: The 2.5 mm hex socket drive ensures secure tool fitting, reducing cam-out and enabling high-torque installation.
• Optimized Thread Design: M3 x 0.5 mm coarse right-hand threads with Class 5g6g fit facilitate quick assembly and secure fastening in a wide range of materials.
• Space-Efficient Partially Threaded Shank: The 18 mm minimum thread length on a 25 mm screw allows for flexible clamping and reduces weight without compromising grip.
• Global Compliance Assurance: Meets DIN 912/ISO 4762 standards and is RoHS 3 & REACH compliant, ensuring reliability and regulatory acceptance worldwide.

Professional Applications & Engineering Value

Engineered for demanding industrial and mechanical assemblies, this M3 socket head cap screw addresses critical challenges in precision fastening. The alloy steel core, hardened to Rockwell C37, prevents stripping and deformation under repetitive stress, while the blue-dyed zinc-plated finish combats corrosion in humid or chemically aggressive environments. Its hex drive design allows for compact installation in tight spaces, commonly used in machinery, automotive components, and electronic enclosures where high tensile strength and vibration resistance are paramount. The metric coarse thread ensures rapid engagement and reduces cross-threading risks, streamlining production workflows and minimizing downtime.
