S-90287A247 10-24 x 1" ASME B18.6.3 Tamper-Resistant One-Way-Drive Steel Round Head Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc plating for extended service life in demanding environments
• Superior holding power from 60,000 psi tensile strength and Rockwell B70 hardness for reliable fastening
• Quick and easy installation with coarse UNC threading and Class 2A fit, reducing assembly time
• Maximum thread engagement due to fully threaded 1" length, ensuring optimal load distribution
• Secure tamper-resistant design featuring a one-way drive style for applications requiring vandalism protection
• Broad industrial compatibility with right-hand thread direction and standard rounded head profile
• Reduced maintenance needs through durable zinc-plated steel construction and consistent performance

Professional Applications & Engineering Value

These 10-24 UNC coarse thread screws with zinc-plated steel construction address critical industrial fastening challenges where corrosion resistance and tamper-proof security are paramount. The rounded head design distributes clamping force evenly while the one-way drive prevents unauthorized removal in public infrastructure, electrical enclosures, and machinery guards. With Class 2A thread fit ensuring consistent engagement and fully threaded 1" length maximizing grip, these screws eliminate loosening in high-vibration environments. Ideal for assembly lines, metal framing, and outdoor equipment, they provide 60,000 psi tensile strength to withstand dynamic loads while maintaining Rockwell B70 hardness to prevent stripping during installation.
