Professional Applications & Engineering Value
These M3 socket head cap screws in 316 stainless steel address critical engineering challenges in precision equipment and corrosive environments. The ultra-low profile socket head design minimizes protrusion while maintaining full torque capability, making them ideal for compact assemblies in electronics, medical devices, and marine hardware. The Class 6g thread fit and metric coarse pitch (0.5mm) ensure rapid assembly and reliable performance under vibration, while the fully threaded design provides consistent clamping force across the entire 16mm length. With exceptional corrosion resistance surpassing standard stainless grades, these fasteners deliver long-term reliability in chemical processing, offshore, and food processing applications where material integrity is paramount.
Specification Summary & Compliance
Manufactured to precise metric standards with M3 x 0.5mm coarse thread and Class 6g thread tolerance for consistent fit. Features include 5.5mm head diameter (±0.127mm tolerance), 2mm hex drive, and 16mm fully threaded length. Mechanical properties include 70,000 psi tensile strength and Rockwell B70 hardness. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for global market acceptance.
