• External hex drive design enables quick installation with common wrench tools

Professional Applications & Engineering Value

These nylon hex head screws with 3/8"-16 UNC coarse threading deliver critical advantages in applications where metal fasteners fail. The off-white nylon plastic construction inherently resists chemical corrosion and galvanic reactions, making them ideal for marine, food processing, and chemical equipment. Their electrical insulation properties prevent short circuits in electrical enclosures and electronic assemblies, while the partial threading design provides enhanced vibration resistance compared to fully threaded alternatives. The external hex drive ensures straightforward installation in confined spaces, and the material's natural lubricity prevents galling during assembly. These features combine to create reliable, maintenance-free fastening solutions for demanding industrial environments.

Specification Summary & Compliance

Manufactured to inch system measurements with Class 2A thread fit tolerance for consistent mating with standard components. Features 3/8"-16 UNC coarse threads with partial threading extending to minimum 1" length. Complies with RoHS 3 (2015/863/EU) regulations restricting hazardous substances. The nylon material maintains dimensional stability across the specified temperature range of -40° to 185°F without requiring additional surface treatments.
