Professional Applications & Engineering Value
Engineered for precision assemblies requiring reliable thread engagement and corrosion resistance, these black-oxide alloy steel screws deliver exceptional performance in industrial equipment, electronic enclosures, and machinery applications. The 6-32 UNC coarse thread configuration provides rapid installation while maintaining Class 3A thread fit accuracy for vibration-prone environments. The combination of 120,000 psi tensile strength and Rockwell C32 hardness ensures these flanged rounded head screws withstand mechanical stress without compromising integrity. The fully threaded design maximizes grip length while the wide button head profile with integrated flange distributes clamping force evenly, preventing surface damage and maintaining seal integrity in critical applications.
Specification Summary & Compliance
This 6-32 UNC thread screw features precision Class 3A thread fit with coarse thread spacing and right-hand threading. Manufactured to inch system specifications with 3/16" length and 0.297" flange diameter. The black-oxide alloy steel construction meets Rockwell C32 hardness and 120,000 psi tensile strength requirements. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for global manufacturing applications.
