Overview

The NSi Industries JSBH183 1-8 x 4 Hex Bolt is a precision-engineered stainless steel fastener designed for heavy-duty industrial, marine, and construction applications. Manufactured from 18-8 stainless steel (AISI 304 equivalent), this hex bolt delivers superior corrosion resistance against rust, chemicals, and extreme temperatures up to 870°C (1600°F). The 1/2"-13 thread size (coarse series) and 4" length provide a secure fit for structural assemblies, machinery mounts, and equipment frameworks where vibration resistance and long-term reliability are critical. Key specifications include a hex head for compatibility with standard wrenches and sockets, a unified thread standard (UNC) for broad interoperability, and a tensile strength of 70,000 PSI minimum. The bolt’s 18-8 composition ensures compliance with ASTM A193 and A276 standards, making it suitable for outdoor installations, chemical processing plants, and coastal environments. Ideal for securing metal-to-metal joints, pipe flanges, and heavy machinery components, the JSBH183 eliminates the need for additional coatings or treatments in corrosive settings. Its 4" length accommodates thick material stacks while maintaining thread engagement for structural integrity. NSi Industries, a US-based manufacturer, guarantees consistent quality and dimensional accuracy for critical fastening applications.
