Professional Applications & Engineering Value
These nylon plastic hex head screws with 2-56 UNC coarse threading solve critical engineering challenges in electrical enclosures, corrosive environments, and weight-sensitive assemblies. The fully threaded design ensures maximum grip length while the black nylon material provides inherent chemical resistance against oils, solvents, and moisture. Unlike metal fasteners, these screws eliminate galvanic corrosion risks in mixed-material assemblies and maintain dimensional stability across the -40° to 185°F temperature range. The external hex drive allows for high-torque installation without stripping, making them ideal for panel mounting, electronic component securing, and marine applications where both electrical isolation and environmental durability are paramount.
Specification Summary & Compliance
Manufactured to UNC thread standards with Class 2A fit tolerance for consistent threading performance. The coarse thread spacing (2-56) ensures rapid installation and superior holding power in plastic and soft materials. All dimensions conform to inch system measurements including 3/8" length, 1/8" head width, and 0.086" thread diameter. Compliant with RoHS 3 (2015/863/EU) regulations, containing no restricted hazardous substances. The fully threaded configuration provides maximum engagement depth while the black color offers UV resistance and aesthetic consistency in visible applications.
