Professional Applications & Engineering Value

This nylon hex head screw addresses critical challenges where metal fasteners typically fail. The off-white nylon material provides inherent corrosion resistance, eliminating rust concerns in humid or chemical-exposed environments while offering complete electrical insulation for sensitive electronic applications. The UNC coarse thread design ensures rapid installation and secure fastening in plastic assemblies, wood, and soft materials where fine threads might strip. With its external hex drive and fully threaded construction, this fastener delivers consistent clamping force across electrical enclosures, marine equipment, and chemical processing applications where non-conductive, non-corrosive properties are essential for system reliability and safety.

Specification Summary & Compliance

This 1/4"-20 x 3/8" nylon hex head screw features UNC coarse threading with Class 2A thread fit for standard inch system applications. Manufactured to precise dimensional standards with right-hand thread direction and fully threaded design. The product is RoHS 3 (2015/863/EU) compliant, ensuring adherence to environmental regulations for hazardous substances.
