Professional Applications & Engineering Value

These 1-72 UNF flat head slotted brass screws deliver exceptional performance in precision engineering applications where corrosion resistance and electrical conductivity are critical. The fine thread spacing combined with Class 2A thread fit provides superior vibration resistance in electronic enclosures, instrumentation, and marine components. The 82° countersink angle ensures perfect flush mounting while the slotted drive style allows for straightforward installation in space-constrained assemblies. Manufactured from high-quality brass material, these screws prevent galvanic corrosion when used with dissimilar metals and maintain reliability in humid or chemical-exposed environments. Their 50,000 psi tensile strength makes them suitable for both structural and non-structural fastening where consistent clamping force is required.

Specification Summary & Compliance

These precision flat head screws feature 1-72 UNF fine threads with Class 2A thread fit per ASME standards, ensuring dimensional accuracy and interchangeability. The manufacturing process adheres to ASME B18.6.3 specifications for dimensional consistency and performance reliability. Environmental compliance is verified through RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance, meeting the latest international regulatory requirements for hazardous substance restrictions. The combination of Rockwell B50 hardness and 50,000 psi tensile strength ensures mechanical performance meets industrial fastening standards for critical applications.
