Professional Applications & Engineering Value

This 3-48 nylon 6/6 hex nut delivers critical engineering advantages where metal fasteners fall short. The nylon 6/6 plastic construction provides inherent corrosion resistance that eliminates galvanic corrosion issues in mixed-material assemblies and harsh chemical environments. The UNC coarse thread profile with Class 2B fit ensures reliable engagement and vibration resistance in industrial equipment, electrical enclosures, and automotive components. With its electrical insulation properties, this nut prevents current flow and grounding issues in electrical applications while operating reliably across the broad -40° to 185°F temperature range. The standard external hex drive allows for quick installation and maintenance using common tools, reducing assembly time and labor costs in production environments.

Specification Summary & Compliance

This inch-system fastener features precise 3-48 UNC coarse threads with Class 2B thread fit for consistent engagement and reliable performance. The nut maintains standard 3/16" width and 1/16" height dimensions compatible with industry tooling. Manufactured from high-grade nylon 6/6 plastic, this component is fully RoHS 3 (2015/863/EU) compliant and meets international environmental standards for restricted substances. The right-hand thread direction follows conventional installation practices, while the external hex drive profile ensures compatibility with standard wrench sets and installation equipment.
