S-90287A245 10-24 x 3/4" ASME B18.6.3 Tamper-Resistant One-Way-Drive Steel Round Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• High tensile strength of 60,000 psi ensures reliable performance in heavy-duty applications and prevents fastener failure
• Rockwell B70 hardness provides excellent wear resistance and maintains thread integrity during repeated installations
• Class 2A thread fit offers optimal assembly clearance for faster installation while maintaining secure fastening
• Coarse UNC threading enables quick engagement and superior pull-out resistance in various materials
• One-way drive style provides tamper-resistant security for applications requiring permanent or restricted access
• Fully threaded design allows for maximum grip length and uniform stress distribution along the entire fastener

Professional Applications & Engineering Value

These 10-24 UNC zinc-plated steel rounded head screws deliver exceptional engineering value for industrial applications where corrosion resistance and high tensile strength are critical. The combination of Rockwell B70 hardness and 60,000 psi tensile strength makes these fully threaded screws ideal for heavy machinery, electrical enclosures, and structural assemblies where vibration resistance and long-term reliability are paramount. The zinc plating provides essential protection against environmental factors, while the coarse thread design ensures quick installation and superior holding power in both metal and composite materials. The rounded head profile with one-way drive offers both aesthetic appeal and tamper-resistant security, making these screws particularly valuable for public infrastructure, transportation equipment, and industrial machinery requiring restricted access.
