Professional Applications & Engineering Value
These 12-28 UNF fine thread rounded head screws deliver exceptional engineering value in precision assembly applications where vibration resistance and corrosion protection are critical. The 18-8 stainless steel composition combined with Class 3A thread fit addresses common industrial challenges of material degradation and loosening under dynamic loads. The fully threaded design ensures maximum surface contact in tapped holes, while the hex drive system provides secure installation in confined spaces. Particularly valuable in electronics enclosures, machinery guards, and precision instrumentation, these button head screws maintain their mechanical properties across temperature variations and corrosive environments, reducing maintenance frequency and replacement costs.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 3A thread tolerance for superior fitment in UNF fine thread applications. The fastener meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring environmental regulatory adherence. Mechanical properties include Rockwell B55 hardness and 70,000 psi tensile strength, providing reliable performance across industrial applications while maintaining corrosion resistance inherent to 18-8 stainless steel composition.
