Key Features & Benefits at a Glance
- Exceptional Strength & Durability: Built from alloy steel with 140,000 psi tensile strength and Rockwell C32 hardness for reliable performance in high-stress applications.
- Superior Corrosion Resistance: Black-oxide finish provides a protective layer, enhancing longevity in various industrial environments.
- Precision Fit & Easy Assembly: Class 5g6g thread fit ensures consistent, secure fastening with minimal play, speeding up installation.
- Space-Saving Design: Ultra-low socket head profile allows for use in compact assemblies where clearance is limited.
- Optimized for Quick Fastening: Coarse thread spacing (0.45mm pitch) enables faster driving and reduced cross-threading risk.
- Versatile & Fully Threaded: Right-hand, fully threaded M2.5 design offers maximum grip and adjustability across the entire length.
- Secure Drive Compatibility: 1.5mm hex drive provides a positive, slip-resistant connection for precise torque application.
Professional Applications & Engineering Value
This M2.5 socket head cap screw is engineered for precision applications where space constraints and reliability are critical. The black-oxide alloy steel construction resists corrosion, making it ideal for electronics, automotive components, and machinery exposed to moderate environmental factors. Its ultra-low profile head and fully threaded design ensure a flush fit and maximum holding power in tight assemblies, reducing the risk of loosening under vibration. The coarse thread with Class 5g6g tolerance allows for quick, accurate installation, minimizing assembly time while maintaining structural integrity in high-performance settings.
Specification Summary & Compliance
This metric screw adheres to precise dimensional standards, including a length tolerance of -0.127mm to 0.127mm and Class 5g6g thread fit for consistent performance. It is manufactured to meet industry specifications for socket head cap screws and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material reliability.
