Professional Applications & Engineering Value

These 0-80 UNF fine thread nylon hex head screws are engineered to address critical challenges in electrical assemblies and corrosive environments. The nylon plastic material inherently resists moisture, chemicals, and galvanic corrosion, eliminating the need for additional coatings. With a fully threaded design and Class 2A thread fit, they provide uniform load distribution and vibration resistance in compact spaces where metal fasteners could cause electrical interference. Ideal for electronic enclosures, instrument panels, and low-strength structural applications, these screws combine electrical insulation with reliable mechanical performance across a broad temperature range from -40°F to 185°F.

Specification Summary & Compliance

This 0-80 UNF fine thread screw features precision Class 2A thread fit per UNF standards, ensuring dimensional accuracy and interchangeability. The 0.06" thread diameter and 3/16" length provide consistent engagement in fine-threaded applications. Manufactured from black nylon plastic with external hex drive and fully threaded construction, these components are RoHS 3 (2015/863/EU) compliant, meeting stringent environmental regulations for hazardous substance restrictions in industrial components.
