5/16-18*1-5/8
5/16-18x1-5/8 threaded rod with 5/16-18 fastener dimensions, 1-5/8 inch bolt specifications for precision fastening. Durable steel construction ensures compatibility with standard mechanical and industrial applications requiring reliable threaded components.

Product Description

The 5/16-18x1-5/8 threaded rod is a precision-engineered fastener designed for industrial assembly, machinery, and construction applications. Featuring 5/16-18 fastener dimensions (5/16" nominal diameter, 18 threads per inch) and a 1-5/8 inch bolt specification for length, it ensures compatibility with standard nuts and mounting hardware. Constructed from high-strength carbon steel or corrosion-resistant stainless steel, this rod operates reliably in temperatures ranging from -20°C to 150°C. Its coarse threading provides superior grip in high-vibration environments, though installation may require specific torque tools for optimal performance. Common uses include structural framing, equipment anchoring, and automotive systems. Key advantages include durability, precise thread alignment, and compliance with ANSI/ASME standards, while limitations involve potential galvanic corrosion in mixed-material setups. The 1-5/8" length enables secure fastening in space-constrained installations.
