Professional Applications & Engineering Value
These 10-32 UNF zinc-plated steel screws deliver exceptional engineering value through their specialized design for vibration-prone industrial applications. The combination of Rockwell B69 hardness and 60,000 psi tensile strength provides reliable performance in machinery, equipment assembly, and automotive components where mechanical stress is constant. The integrated external-tooth lock washer actively resists loosening under sustained vibration, while the fine UNF threads and Class 2A fit ensure precise engagement in tapped holes. The zinc-plated finish offers corrosion resistance in moderate environments, making these rounded head screws ideal for electrical enclosures, control panels, and industrial machinery requiring both security and accessibility for maintenance.
Specification Summary & Compliance
This 1" length screw features precise Class 2A thread fit with 10-32 UNF fine threads and right-hand threading direction. Manufacturing complies with ASME B18.13 specifications for dimensional accuracy and performance. The product meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) regulations, ensuring environmental responsibility while delivering reliable mechanical performance with fully threaded construction and integrated external-tooth lock washer system.
