• Exceptional mechanical strength with 100,000 psi tensile strength and Rockwell B96 hardness for reliable, long-term performance
• Maximum holding power and simplified installation achieved through fully threaded design and coarse 0.45 mm pitch
• Secure, flush-mount fastening provided by the low-profile, rounded button head style
• Precise, reliable thread engagement ensured by Class 4g6g thread fit for consistent assembly quality
• Broad industry compatibility with compliance to ASME B18.3.4M, RoHS 3, and REACH regulations

Professional Applications & Engineering Value

This M2.6 metric screw is engineered to address critical challenges in precision assembly and demanding environments. The 18-8 Stainless Steel material, combined with a passivated finish, provides excellent resistance to oxidation and chemical exposure, making it suitable for electronics, medical devices, and outdoor equipment where moisture is a concern. The Torx T8 drive offers superior torque transfer compared to Phillips or slotted drives, minimizing tool slippage and head stripping during high-torque applications. Its fully threaded body and coarse pitch ensure rapid installation and robust clamping force in thin materials or pre-tapped holes. The rounded button head design sits flush against surfaces, reducing snagging risks and providing a clean, professional appearance in finished products.
