Overview

The Minerallac Company 558248USJ is a precision-engineered Grade 8 hex head cap screw designed for heavy-duty industrial applications requiring maximum tensile strength and corrosion resistance. This 1/2-13 x 1-1/2 inch fastener features a fully threaded design with a yellow zinc plating, providing superior protection against rust and corrosion in both indoor and outdoor environments. The Grade 8 classification ensures a tensile strength of 150,000 PSI, making it ideal for critical fastening applications in machinery, construction, and industrial equipment where reliability and durability are paramount. Key specifications include a 1/2-inch diameter with 13 threads per inch (TPI), a 1.5-inch overall length, and a hex head design for secure wrench engagement. The yellow zinc finish offers enhanced corrosion resistance compared to standard zinc plating, extending service life in harsh conditions. Common applications include securing heavy machinery components, structural assemblies, electrical enclosures, and equipment mounting where high-strength fastening is required. The fully threaded design allows for versatile use in both through-hole and blind-hole applications, providing flexibility in design and installation. Each 558248USJ unit is individually packaged and identified by its SKU for easy inventory management and procurement.
