S-91870A717 6-32 x 1" ASME B18.3 Tamper-Resistant Torx Plus Stainless Steel Flat Head Screws

Key Features & Benefits at a Glance

• Enhanced tamper resistance with Torx Plus IPR15 drive for secure installations in restricted-access environments
• Superior corrosion protection from 18-8 stainless steel construction and passivated finish, ideal for harsh industrial conditions
• Maximum load distribution through full threading and Class 3A thread fit, ensuring reliable fastening in high-vibration applications
• Optimized flush mounting with standard flat head profile and 82° countersink angle for seamless surface integration
• Exceptional mechanical strength delivering 70,000 psi tensile strength and Rockwell B70 hardness for heavy-duty use
• Regulatory compliance assurance meeting ASME B18.3 standards and environmental directives (RoHS 3/REACH)
• Simplified installation with right-hand coarse threading (UNC 6-32) for efficient assembly in time-sensitive operations

Professional Applications & Engineering Value

Engineered for high-security industrial applications, these 6-32 UNC flat head screws address critical challenges in public infrastructure, machinery guarding, and electronic enclosures where unauthorized access prevention is paramount. The tamper-resistant Torx Plus drive (IPR15) combined with 18-8 stainless steel material and passivated finish creates a durable barrier against both physical tampering and environmental degradation. The Class 3A thread fit and fully threaded design maintain clamping force under dynamic loads, while the standardized flat head profile ensures flush mounting without compromising structural integrity. These screws deliver engineering reliability in HVAC systems, transportation equipment, and manufacturing assemblies where vibration resistance and long-term performance are non-negotiable.
