Professional Applications & Engineering Value
Engineered for demanding industrial settings, these 10-32 UNF nylon hex head screws solve critical challenges in electrical and corrosive environments. The black nylon plastic material inherently resists moisture, chemicals, and galvanic corrosion, eliminating the need for protective coatings. With full threading and Class 2A fit, they ensure uniform load distribution and vibration resistance in assemblies requiring fine thread precision. The external hex drive facilitates high-torque installation without stripping, making them ideal for enclosures, panels, and equipment where electrical insulation and non-magnetic properties are essential. Their operational range from -40° to 185°F supports reliability in outdoor, automotive, and HVAC applications.
Specification Summary & Compliance
This screw adheres to UNF fine thread standards with a 10-32 thread size and Class 2A thread fit for consistent dimensional accuracy. It is fully threaded with a length of 1/4", head height of 1/8", and head width of 5/16". Compliance with RoHS 3 (2015/863/EU) ensures the absence of hazardous substances, meeting global environmental and safety regulations for industrial components.
