Professional Applications & Engineering Value
This M12 flat head hex screw delivers critical engineering solutions for heavy-duty industrial applications where high tensile strength and corrosion resistance are paramount. The zinc-plated alloy steel construction provides superior protection against environmental degradation, while the Class 10.9 strength rating ensures reliable performance under extreme mechanical stress. The metric coarse threading (1.75mm pitch) with Class 6g fit prevents loosening from vibration, making it ideal for machinery, structural frameworks, and equipment assembly. The combination of fully threaded design and 90° countersink angle allows for flush mounting in predrilled holes, creating secure, low-profile connections that withstand rigorous operational demands in manufacturing, construction, and automotive industries.
Specification Summary & Compliance
This fastener maintains precise Class 6g thread fit according to metric standards with M12 x 1.75mm coarse threading. Manufacturing complies with DIN 7991 specifications for dimensional accuracy and performance requirements. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant regarding substance restrictions, ensuring environmental responsibility and global market acceptance for industrial procurement.
