Professional Applications & Engineering Value
These zinc-plated steel rounded head screws deliver critical reliability for industrial assemblies where vibration resistance and environmental durability are paramount. The 12-24 UNC coarse thread configuration ensures rapid installation while maintaining secure fastening in materials prone to stripping. With fully threaded construction and Class 2A thread fit, these screws provide maximum thread engagement for distributed load bearing. The combination of 60,000 psi tensile strength and zinc plating addresses common failure points in machinery, electrical enclosures, and structural components exposed to moderate corrosion. The No. 3 Phillips drive and pan head profile offer familiar installation while the rounded design minimizes snagging in confined spaces.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit and 12-24 UNC coarse thread specifications. Complies with ASME B18.6.3 mechanical and dimensional requirements. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for hazardous substance restrictions. Features consistent 1/4" length and standardized head dimensions for reliable interchangeability.
