Professional Applications & Engineering Value
These 0-80 UNF flat head screws deliver critical engineering solutions where space constraints and surface finish requirements are paramount. The zinc-plated steel construction provides essential corrosion protection for industrial equipment, electronic enclosures, and precision machinery components. The fine thread configuration offers superior resistance to vibrational loosening in dynamic applications, while the 82° countersink angle ensures flush mounting in sheet metal, plastic components, and machined surfaces. The combination of 60,000 psi tensile strength and Class 2A thread fit guarantees reliable performance in high-stress applications, making these Phillips drive screws ideal for assembly lines requiring consistent, repeatable fastening solutions.
Specification Summary & Compliance
Manufactured to exacting ASME B18.6.3 standards with precision Class 2A thread fit for consistent engagement and optimal performance. The 0-80 UNF fine threads maintain tight tolerances while the 1/4" length provides full threading for maximum holding capacity. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and global market acceptance for industrial and commercial applications.
