Key Features & Benefits at a Glance
- Exceptional tensile strength of 170,000 PSI ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
- Superior corrosion resistance from the black-oxide finish on alloy steel prolongs service life in harsh industrial environments.
- High hardness rating (Rockwell C37) provides excellent wear resistance, maintaining thread integrity through repeated use.
- Precision Class 5g6g thread fit offers consistent engagement and ease of assembly, minimizing installation time.
- Standard hex socket drive (6mm) allows for secure tool engagement and high torque application without slippage.
- Full threading along the 30mm length enables flexible positioning and strong clamping force across the entire fastener.
- Compliance with DIN 912/ISO 4762 standards guarantees dimensional accuracy and interchangeability for global engineering projects.
Professional Applications & Engineering Value
This M8 socket head cap screw is engineered to address critical challenges in demanding sectors such as machinery, automotive, and heavy equipment. The black-oxide alloy steel construction combats rust and oxidation, ideal for environments exposed to moisture or chemicals. With a coarse thread (1.25mm pitch) and right-hand thread direction, it resists loosening under vibration and ensures quick assembly. The Class 12.9 strength rating and fully threaded design provide robust clamping force, preventing joint failure in high-load scenarios. Its hex socket drive facilitates access in confined spaces, enhancing installation efficiency while meeting strict DIN 912 and ISO 4762 specifications for reliability.
Specification Summary & Compliance
This fastener features an M8 x 1.25mm coarse thread with a Class 5g6g thread fit per ISO metric standards, ensuring precise dimensional tolerance. It is manufactured in compliance with DIN 912/ISO 4762 for socket head cap screws, covering head diameter (13mm), drive size (6mm), and length (30mm). The product adheres to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and safe for industrial use.
