Overview

The NSI Industries 166-G is a zinc die-cast grounding locknut designed for secure electrical bonding in industrial and commercial systems. Engineered to replace standard locknuts, it eliminates the need for additional hardware while ensuring reliable grounding and bonding connections. The 166-G accommodates lugs from 14 AWG to 1/0 AWG and fits 2-inch trade size conduits or hubs, providing a precise fit for tight installations. Its ball-burnished, mirror-smooth finish resists corrosion and mechanical stress, making it ideal for demanding environments. Certified to UL Standard 514B and CSA C22.2 No. 18.3, the 166-G meets Federal Specification A-A-50553 and NEMA FB-1 standards. ETL listed for use with all Bridgeport Fittings connectors, this locknut simplifies installation by combining grounding and locking functions in a single component. The zinc die-cast construction ensures durability, while the tin-plated aluminum lug provides superior conductivity. Suitable for applications requiring robust grounding solutions, the 166-G is a cost-effective alternative to traditional grounding bushings and locknuts.
