Professional Applications & Engineering Value
These 4-40 UNC nylon plastic hex head screws address critical challenges in industries where metal fasteners fail. The off-white nylon material inherently resists corrosion from moisture, chemicals, and UV exposure, making them ideal for outdoor equipment, marine components, and chemical processing installations. Their electrical insulation properties prevent short circuits in electronic enclosures, PCB mounting, and electrical control panels. The coarse UNC thread and Class 2A thread fit enable quick assembly in plastics and soft materials without stripping, while the external hex drive allows high torque application using standard tools. Engineered for temperature resistance from -40°F to 185°F, these screws maintain dimensional stability in automotive, HVAC, and consumer goods applications where thermal cycling occurs.
Specification Summary & Compliance
This product features a 4-40 UNC coarse thread with Class 2A thread fit for standard inch-system applications, ensuring dimensional accuracy per unified screw thread standards. The fully threaded 3/16" length and external hex head (1/16" height, 3/16" width) provide consistent mechanical performance. Manufacturing adheres to industry specifications for nylon plastic fasteners, and compliance with RoHS 3 (2015/863/EU) is verified, meeting environmental regulations for hazardous substance restrictions.
