Overview

The NSi Industries JCB21SS Stainless Steel Carriage Bolt is a precision-engineered fastener designed for wood and metal applications requiring a flush, secure fit. Constructed from 18-8 grade stainless steel, this bolt delivers exceptional corrosion resistance and long-term durability in outdoor, marine, and industrial environments. The mushroom head design ensures a smooth, finished appearance while preventing over-tightening, making it ideal for furniture, decking, and structural connections. The square neck under the head locks into the material, eliminating rotation during installation for consistent torque application. Key specifications include a 2-1/2-inch overall length, 5/16-18 thread size with right-hand threading, and a total thread length of 1.5 inches. The 18-8 grade stainless steel composition provides a tensile strength of approximately 80,000 PSI, balancing strength with corrosion resistance. This bolt is packaged in a convenient 100-piece box for bulk applications, reducing procurement time and inventory overhead. Compatible with standard 5/16-inch washers and nuts, it meets ASTM F593 standards for stainless steel fasteners. Ideal for wood-to-wood and wood-to-metal connections, the JCB21SS excels in deck construction, cabinetry, playground equipment, and agricultural machinery. Its non-marring head design prevents surface damage while maintaining structural integrity. Unlike hex-head bolts, the mushroom head reduces snag hazards and improves aesthetics in visible applications. For projects requiring frequent disassembly, the 18-8 grade offers superior resistance to galling compared to lower-grade stainless steels. Trust NSi Industries, a U.S.-based manufacturer, for fasteners that meet rigorous industry standards and deliver consistent performance in demanding conditions.
