Professional Applications & Engineering Value
Engineered for demanding industrial applications, these M16 hex screws combine black-oxide alloy steel construction with Class 10.9 strength to solve critical fastening challenges. The fully threaded design with coarse 2mm pitch ensures rapid installation in heavy machinery, structural steel frameworks, and automotive assemblies where vibration resistance is paramount. The rounded head button style with 10mm hex drive provides optimal torque transmission while maintaining a low-profile appearance. Rockwell C32 hardness and 140,000 psi tensile strength guarantee reliable performance under extreme loads, making these metric screws ideal for applications requiring repeated disassembly and reassembly without compromising fastener integrity.
Specification Summary & Compliance
Manufactured to ISO 7380 standards with Class 6g thread fit tolerance for precise dimensional accuracy. The M16x2mm coarse thread configuration ensures compatibility with standard metric components. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, verified through rigorous testing protocols. Class 10.9 strength rating confirms adherence to international mechanical property standards for high-strength fasteners.
