Professional Applications & Engineering Value
These zinc-plated steel slotted pan head screws deliver critical performance where corrosion resistance and mechanical reliability are paramount. The UNC coarse thread design prevents cross-threading during assembly in high-volume production lines, while the Class 2A thread fit maintains consistent clamping force under vibration. The rounded pan head profile offers a low-profile finish that minimizes snagging in confined spaces. Ideal for industrial equipment assembly, electrical enclosures, and machinery maintenance, these screws provide lasting fastening solutions where exposure to moisture or chemicals would compromise ordinary fasteners. The combination of 60,000 psi tensile strength and full threading ensures uniform load distribution across joined components.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread fit tolerances for consistent dimensional accuracy. The UNC coarse thread (6-32 size) features right-hand direction and 0.138" thread diameter. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications.
