Professional Applications & Engineering Value
These 12-24 UNC flat head screws deliver critical engineering solutions for industrial applications where flush mounting and high tensile strength are paramount. The zinc-plated steel construction provides essential corrosion protection, extending service life in manufacturing equipment, machinery assembly, and structural frameworks. The coarse UNC threading combined with Class 2A fit ensures rapid installation while maintaining precision alignment, reducing assembly time and preventing thread damage. The fully threaded design maximizes load distribution, making these flat head machine screws ideal for applications requiring consistent clamping force across varying material thicknesses. With 82° countersink angle compatibility, they seamlessly integrate into standardized components while maintaining clean aesthetic profiles.
Specification Summary & Compliance
Manufactured to exacting ASME B18.6.3 standards, these screws feature precision UNC coarse threads with Class 2A fit tolerances for consistent performance. The 12-24 thread size and 2" length maintain dimensional accuracy across production batches. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures responsible manufacturing practices. The Rockwell B70 hardness rating and 60,000 psi tensile strength validate mechanical performance for industrial-grade applications requiring reliable fastening solutions.
