Professional Applications & Engineering Value

These nylon hex head screws deliver exceptional value in applications where metal fasteners fail. The off-white nylon plastic construction provides inherent corrosion resistance, making them ideal for chemical processing, marine, and outdoor equipment. Their electrical insulation properties are critical in electrical enclosures, control panels, and electronic assemblies where current isolation is mandatory. The UNC coarse thread spacing ensures rapid installation and superior holding power in plastic and soft materials. With external hex drive compatibility, maintenance teams can achieve high torque application using standard tools, while the 2" length with partial threading offers optimal grip range for various material thicknesses.

Specification Summary & Compliance

Manufactured to precise inch system specifications with Class 2A thread fit tolerance ensuring consistent performance with standard mating components. Features 5/16"-18 UNC coarse thread spacing with minimum thread length of 7/8" on a 2" overall length. Fully compliant with RoHS 3 (2015/863/EU) regulations, containing no restricted hazardous substances. The partially threaded design follows industrial fastening standards for controlled clamping applications.
