Overview

The NSi Industries J1520 Spring Wing Toggle Bolt is a precision-engineered fastening solution for hollow wall and drywall applications where reliable load-bearing support is critical. Constructed from high-strength steel with a zinc chromate finish, this toggle bolt delivers superior corrosion resistance and long-term durability in demanding industrial, commercial, and residential environments. The 4-inch length and 3/8-16 right-hand thread provide secure anchoring in materials up to 3/8-inch diameter holes, while the integrated spring wing expands behind the wall to distribute load evenly and prevent pull-through. The round head with slot/Phillips drive type ensures compatibility with standard screwdrivers and power tools, enabling quick and efficient installation without specialized equipment. Each J1520 is packaged 25 per unit for bulk handling convenience, making it ideal for contractors, electricians, plumbers, and maintenance crews who require consistent performance across large projects. Typical applications include mounting electrical boxes, conduit straps, HVAC ductwork, signage, shelving, and machinery brackets where hollow wall or drywall anchoring is required. The zinc chromate finish provides an additional layer of protection against rust and oxidation, extending service life in humid or corrosive environments. Compatible with standard 3/8-inch drill bits, the J1520 simplifies installation by eliminating the need for pre-tapped holes or complex anchor systems. Trust NSi Industries, a U.S.-based manufacturer, for fasteners that meet rigorous industry standards and deliver predictable holding power in critical applications.
