Professional Applications & Engineering Value
This M12 hex head screw delivers critical engineering solutions through its zinc-plated steel construction and expanding sleeve locking mechanism. The combination addresses common industrial challenges including vibration-induced loosening in machinery, structural assemblies, and equipment frames. The coarse thread design enables rapid installation in various materials while maintaining Class 8.8 strength for structural integrity. With 110,000 PSI tensile strength and corrosion-resistant plating, these metric screws provide long-term reliability in construction, manufacturing, and heavy equipment applications where fastener failure is not an option. The fully threaded design ensures maximum grip length across the specified material thickness range.
Specification Summary & Compliance
Manufactured to ISO 4017 (equivalent to DIN 933) standards with Class 6g thread fit tolerance for precision engagement. The fastener meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring environmental and safety standards are maintained. Features include M12x1.75mm coarse thread, 2-1/8" length, and expanding sleeve locking technology. Designed for use with 13/16" drill bits and compatible with material thicknesses from 5/16" to 1".
