Key Features & Benefits at a Glance
- Exceptional tensile strength of 170,000 PSI ensures reliable performance under extreme loads, minimizing the risk of fastener failure in demanding applications.
- Superior corrosion resistance provided by the Black-Oxide finish on alloy steel, extending service life in harsh industrial environments.
- High hardness rating of Rockwell C37 offers excellent wear resistance and maintains thread integrity during repeated installation and removal.
- Precision Class 5g6g thread fit guarantees smooth assembly and a secure, vibration-resistant connection for consistent performance.
- Partially threaded M8 x 1.25mm coarse pitch design with a 28mm minimum thread length allows for optimal clamping force and easier alignment in assemblies.
- Standard hex socket drive (6mm) enables high torque application and secure tool engagement, reducing the risk of stripping and simplifying maintenance.
- Full compliance with DIN 912/ISO 4762 standards ensures dimensional accuracy and interchangeability, backed by RoHS 3 and REACH environmental regulations.
Professional Applications & Engineering Value
This M8 Socket Head Cap Screw is engineered for high-stress applications where reliability is non-negotiable. The Class 12.9 alloy steel construction, combined with a Black-Oxide surface treatment, provides robust resistance to corrosion and wear, making it ideal for machinery, automotive assemblies, and heavy equipment. The partially threaded metric design with a coarse 1.25mm pitch ensures quick installation and superior grip in materials prone to vibration loosening. Its 120mm length and hex drive facilitate access in confined spaces, reducing assembly time and enhancing structural integrity in precision engineering projects.
Specification Summary & Compliance
This screw features an M8 x 1.25mm thread with a Class 5g6g thread fit per ISO metric standards, ensuring precise tolerance and compatibility. It is manufactured to meet DIN 912 (ISO 4762) specifications for socket head cap screws, guaranteeing dimensional consistency. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, affirming its safety and environmental responsibility for global industrial use.
