Professional Applications & Engineering Value
This M6 metric screw combines black-oxide alloy steel construction with a tamper-resistant Torx drive to address critical needs in industrial assembly and security-sensitive applications. The fully threaded design with Class 6g thread fit ensures maximum thread engagement and load distribution, preventing loosening in high-vibration machinery. The rounded button head profile provides a low-profile finish that eliminates protrusions in confined spaces while maintaining structural integrity. Engineered for industrial fastening in electronics enclosures, automotive components, and public infrastructure, these security screws deliver reliable performance where unauthorized access prevention and durability are paramount.
Specification Summary & Compliance
Manufactured to ASME B18.3.4M and ISO 7380 specifications with Class 6g thread tolerance for precision fit. The M6 x 1 mm coarse thread configuration ensures compatibility with standard metric components. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming suitability for global industrial markets and regulated applications.
