Professional Applications & Engineering Value
These 10-24 UNC flat head screws deliver critical performance advantages in industrial settings where corrosion resistance and mechanical reliability are paramount. The 18-8 stainless steel base material combined with black-oxide passivated finish creates a durable barrier against moisture, chemicals, and environmental degradation, significantly extending service life in manufacturing equipment, electrical enclosures, and outdoor assemblies. The Class 3A thread fit and coarse UNC threading provide superior resistance to loosening under vibration, while the 82° countersink and flat head design ensure seamless integration into precision-machined components. With 70,000 psi tensile strength, these fully threaded screws maintain clamping force in high-stress applications, reducing maintenance frequency and downtime.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit and UNC coarse thread profile. Features include 10-24 thread size, 1/2" length, 82° countersink angle, and Rockwell B55 hardness. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations.
