Professional Applications & Engineering Value

This M6 metric hex head screw delivers critical sealing performance for demanding industrial applications where pressure integrity is paramount. The 18-8 stainless steel construction provides excellent corrosion resistance in chemical processing, marine, and food equipment environments, while the silicone rubber O-ring maintains reliable seals against fluids and gases up to 20,000 psi. The Class 6g thread fit ensures precise engagement in metric coarse threading applications, preventing loosening under vibration in machinery, hydraulic systems, and pneumatic equipment. With fully threaded design and external hex drive, installation is streamlined for maintenance efficiency in confined spaces, making it ideal for pressure vessels, pump assemblies, and industrial valve applications requiring both structural integrity and fluid containment.

Specification Summary & Compliance

This metric hex head screw features M6 x 1mm coarse thread spacing with Class 6g thread fit per ISO metric standards, ensuring dimensional accuracy and interchangeability. The manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental safety and material transparency. With 18mm length and fully threaded configuration, it maintains consistent 80,000 psi tensile strength across the entire fastener length, suitable for maximum hole diameters of 6.655 mm in engineered assemblies.
