Overview

The Minerallac Company 3/8-16 x 1-1/2" Grade 5 Hex Bolt (SKU: 55425) is a high-strength industrial fastener engineered for heavy-duty applications requiring reliable load-bearing performance. Constructed from medium carbon steel and quenched/tempered for enhanced durability, this bolt features a hexagonal head for secure torque application and a fully threaded shank for maximum grip. The zinc plating provides corrosion resistance, making it suitable for indoor and outdoor use in moderate environments. Key specifications include a 3/8" diameter with 16 threads per inch (TPI) and a 1.5" length, ensuring compatibility with standard 3/8-16 threaded holes. The Grade 5 rating indicates a tensile strength of approximately 120,000 PSI, offering superior performance compared to lower-grade fasteners. This bolt is ideal for construction, machinery assembly, electrical conduit systems, and general fabrication where robust fastening is critical. Manufactured in the USA by Minerallac Company, a trusted name in industrial fasteners since 1926, this bolt meets stringent quality standards for precision and reliability. Pair with Minerallac Grade 5 Hex Nuts (see page 57 in their catalog) for optimal performance.
