Professional Applications & Engineering Value

Engineered for demanding industrial environments, these nylon plastic hex head screws deliver critical performance advantages where metal fasteners fail. The non-conductive properties make them ideal for electrical enclosures, control panels, and marine equipment where electrical isolation is paramount. The corrosion-resistant nylon material withstands exposure to chemicals, saltwater, and moisture without degradation, eliminating galvanic corrosion concerns. With UNC coarse threading and Class 2A thread fit, these screws provide reliable fastening in plastics, wood, and soft metals while the partial threading offers superior pull-out resistance. The external hex drive ensures maximum torque transmission for secure installations in confined spaces.

Specification Summary & Compliance

These inch system fasteners feature precise 1/2"-13 UNC coarse thread with Class 2A thread fit tolerance, ensuring consistent performance across applications. The 3" length with 1 1/4" minimum thread length provides optimal engagement depth. Manufactured from off-white nylon plastic, these screws maintain dimensional stability across the specified -40° to 185°F temperature range. Compliance with RoHS 3 (2015/863/EU) standards ensures environmental responsibility and global market acceptance for your assemblies.
