• High tensile strength of 100,000 psi ensures reliable fastening in demanding mechanical applications
• Excellent corrosion resistance from 18-8 stainless steel construction, ideal for harsh industrial environments
• Precision Class 6g thread fit provides consistent engagement and vibration resistance in coarse 0.8 mm pitch applications
• Standard hex socket drive allows for easy installation with common 4 mm hex tools in confined spaces
• Comprehensive compliance with ASME B18.3, DIN 912, ISO 4762 standards and RoHS/REACH environmental regulations

Professional Applications & Engineering Value

This M5 socket head cap screw with Viton® sealing addresses critical engineering challenges in fluid systems and pressure vessels where leakage prevention is paramount. The 18-8 stainless steel construction combined with the fluoroelastomer O-ring creates a robust sealing solution that maintains performance across extreme temperature fluctuations from -20° to 400° F. The partially threaded design with coarse 0.8 mm pitch ensures secure fastening in high-vibration industrial equipment, while the 40 mm length provides sufficient engagement for structural integrity. These metric hex socket screws are engineered for applications requiring reliable high-pressure sealing up to 1500 psi in hydraulic systems, pneumatic controls, and processing equipment where corrosion resistance and long-term durability are essential.
