• High tensile strength of 70,000 psi ensures reliable load-bearing capacity for demanding industrial applications
• Precise Class 3A thread fit delivers excellent engagement and reduces the risk of cross-threading during installation
• Easy installation and removal with hex drive design that provides superior torque transfer and tool grip
• Durable Rockwell B55 hardness offers excellent wear resistance and extends service life under repeated use
• Standard 82° countersink angle allows for flush mounting in various materials without protruding heads

Professional Applications & Engineering Value

These 10-24 UNC flat head screws are engineered to address critical fastening challenges in industrial settings where vibration loosening and corrosion are common failures. The nylon patch thread locker embedded in the coarse UNC threads creates consistent friction that prevents back-out under dynamic loads, making them ideal for machinery, automotive assemblies, and electronic enclosures. Manufactured from 18-8 stainless steel, they provide exceptional resistance to rust and chemical exposure, ensuring reliability in humid or corrosive environments. The hex drive design enables high-torque installation with standard tools, while the fully threaded construction offers maximum grip length for secure connections in metal, plastic, and composite materials. These features combine to reduce maintenance frequency and enhance structural integrity in heavy-duty fastening applications.

Specification Summary & Compliance

This flat head screw features precise Class 3A thread fit with UNC coarse threading and a length of 3/8". It complies with ASME B18.3, ASTM F879, and MIL-DTL-18240 manufacturing specifications, ensuring consistent quality and dimensional accuracy. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental and safety standards for industrial components.
