S-96075A223 1/4"-20 x 1" ASME B18.3 Tamper-Resistant Torx Steel Button Head Screws

Key Features & Benefits at a Glance

• Enhanced tamper-resistance with specialized T27 Torx drive that deters unauthorized access in security-sensitive environments
• Superior corrosion protection through black-oxide coating on alloy steel, extending service life in demanding industrial conditions
• Maximum thread engagement with full threading and Class 3A fit ensuring reliable fastening in high-vibration applications
• Exceptional mechanical strength with 130,000 psi tensile strength and Rockwell C38 hardness for heavy-duty load requirements
• Optimized installation efficiency through coarse UNC threading that reduces cross-threading risks during assembly
• Regulatory compliance assurance meeting ASME B18.3 standards and international environmental regulations (RoHS 3, REACH)
• Secure rounded head design providing smooth surface profile while maintaining tamper-resistant properties

Professional Applications & Engineering Value

Engineered for critical applications where security fastening and structural integrity are paramount, these black-oxide alloy steel screws deliver exceptional performance in access control systems, industrial machinery, and public infrastructure. The tamper-resistant Torx drive (T27) specifically addresses vandalism concerns while maintaining precise torque transmission during installation. With Class 3A thread fit and coarse UNC threading, these fasteners prevent loosening under dynamic loads while enabling rapid assembly in production environments. The combination of 130,000 psi tensile strength and Rockwell C38 hardness ensures reliable performance in high-stress applications, from heavy equipment manufacturing to security enclosure assembly, where fastener failure is not an option.
