• Comprehensive regulatory compliance meeting ASME B18.3, RoHS 3, and REACH standards for global industrial applications

Professional Applications & Engineering Value

These 10-24 UNC flat head screws with Torx Plus drive deliver exceptional performance in demanding industrial environments. The black-oxide alloy steel construction provides superior corrosion protection while maintaining high tensile strength (140,000 psi) and hardness (Rockwell C39). The Class 3A thread fit ensures precise engagement in critical assemblies, reducing the risk of vibration-induced loosening. The fully threaded design with coarse spacing enables rapid installation and reliable clamping in various materials. Engineered with an 82° countersink angle, these screws sit flush with surfaces while the Torx Plus IP25 drive system prevents stripping during high-torque applications. Ideal for machinery, equipment manufacturing, and structural assemblies requiring ASME B18.3 compliance and environmental regulation adherence.
