Professional Applications & Engineering Value

Engineered for industrial applications requiring reliable, non-conductive fastening solutions, these 3/8"-16 UNC hex head screws deliver exceptional value through their nylon plastic composition and specialized design. The black nylon material provides inherent corrosion resistance, making these plastic fasteners ideal for chemical processing, marine environments, and outdoor equipment where metal corrosion would compromise safety. The external hex drive configuration ensures maximum torque application without stripping, while the coarse UNC threading maintains secure holding power in plastic housings, electrical enclosures, and composite materials. These partially threaded screws offer precise clamping force control, preventing material damage in sensitive assemblies while the temperature range from -40° to 185°F ensures performance stability across seasonal variations and industrial thermal cycles.

Specification Summary & Compliance

Manufactured to precise inch system dimensions with Class 2A thread fit tolerance for consistent engagement and reliable performance. Features 3/8"-16 UNC coarse threading with partial threading configuration and complies with RoHS 3 (2015/863/EU) environmental regulations. The external hex drive with 9/16" head width and 17/64" head height provides standardized tool compatibility, while the 2" length with 1" minimum thread length ensures proper fastening depth across various material thicknesses.
