- Exceptional corrosion resistance from 18-8 stainless steel construction, ensuring long-term reliability in harsh industrial environments
- High tensile strength of 100,000 psi and Rockwell B85 hardness for reliable fastening under heavy loads and vibration
- Precise Class 6g thread fit provides consistent engagement and reduces the risk of cross-threading during assembly
- Partially threaded design allows for optimal clamping force distribution and secure positioning in assemblies
- Standard hex socket drive enables high-torque installation with common tools, reducing assembly time and tool slippage
- Broad compliance with international standards including ASME B18.3, DIN 912, and ISO 4762 for guaranteed interchangeability and quality
Professional Applications & Engineering Value
These M8 metric socket head cap screws deliver critical sealing solutions for industrial equipment exposed to fluids, gases, and pressure variations. The combination of 18-8 stainless steel material and Buna-N rubber O-ring creates a reliable barrier against contaminants and leakage in hydraulic systems, pneumatic components, and machinery enclosures. With their coarse thread pitch and Class 6g thread fit, these screws provide rapid assembly while maintaining vibration resistance in automotive, manufacturing, and processing applications. The partially threaded configuration ensures precise clamping without compromising the sealing integrity, making them ideal for flange connections, pump housings, and valve assemblies where pressure containment is essential.
Specification Summary & Compliance
This M8 x 1.25mm x 45mm socket head cap screw features Class 6g thread tolerance per metric standards with a minimum thread length of 24mm. Manufacturing specifications conform to ASME B18.3, DIN 912, and ISO 4762 for dimensional accuracy and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets.
