Professional Applications & Engineering Value
These zinc-plated steel rounded head screws deliver exceptional performance in industrial settings where corrosion resistance and mechanical reliability are paramount. The 2-56 UNC coarse thread configuration ensures rapid installation while maintaining secure fastening in materials where fine threads might compromise integrity. With fully threaded construction and 60,000 psi tensile strength, these Phillips drive screws distribute stress evenly across the entire fastener length, preventing localized failure points. The pan head profile provides adequate bearing surface without protruding excessively, making them ideal for machinery, electrical enclosures, and assembly applications where space optimization and corrosion protection are critical engineering considerations.
Specification Summary & Compliance
Manufactured to precise Class 2A thread fit tolerances with UNC coarse threading standards, these screws maintain dimensional accuracy for consistent performance. Compliance with ASME B18.6.3 manufacturing specifications ensures mechanical reliability, while RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) certifications guarantee environmental responsibility and regulatory adherence for global industrial applications.
