Professional Applications & Engineering Value
These 6-32 UNC Nylon Plastic Hex Head Screws deliver critical solutions for industries requiring non-conductive, corrosion-resistant fasteners. The coarse UNC thread and Class 2A fit ensure rapid installation and reliable performance in plastics, composites, and sheet metal assemblies, reducing the risk of cross-threading and material stripping. With a temperature range of -40° to 185°F, they withstand environmental shifts in outdoor enclosures, automotive components, and electrical panels. The external hex drive and fully threaded design enable high-torque application and full-length engagement, making them ideal for securing sensitive electronics, HVAC systems, and consumer appliances where metal screws could cause galvanic corrosion or signal interference.
Specification Summary & Compliance
These screws adhere to UNC coarse thread standards with a Class 2A thread fit for consistent dimensional accuracy. Manufactured in the inch system, they feature a 6-32 thread size, 3/8" length, and 1/4" head width. Compliance includes RoHS 3 (2015/863/EU), ensuring they are free from hazardous substances for safe use in global markets.
