Rods, Studs, and Keystock

Threaded rods are versatile fasteners used in construction, manufacturing, and assembly applications. Common uses include hanging HVAC systems, mounting electrical conduit, concrete anchoring, and creating adjustable support systems. Their continuous threading allows for precise adjustment and secure connections using nuts and washers.

Grade 2 threaded rod is suitable for general-purpose applications with moderate stress requirements. Grade 5 is heat-treated for higher strength and is recommended for applications requiring greater tensile strength and durability. Grade 5 typically offers about 40% higher tensile strength compared to Grade 2.

Yes, threaded rod can be cut to custom lengths using appropriate cutting tools like a bandsaw or bolt cutter. After cutting, it's recommended to clean up the threads with a file or die nut to ensure proper thread engagement. We also offer custom cutting services for your convenience.

For outdoor applications, we recommend either hot-dip galvanized or stainless steel threaded rod. Hot-dip galvanized provides good corrosion resistance at a lower cost, while 316/304 stainless steel offers superior protection in harsh environments, especially near coastal areas or chemical exposure.

Consider three main factors: load requirements, environmental conditions, and compatibility with existing hardware. For structural applications, consult local building codes and engineering specifications. Our technical team can assist in selecting the appropriate diameter and grade for your specific needs.

Threaded rods have continuous threading along their entire length and are typically cut to size for installation with nuts on both ends. Threaded studs, by contrast, are pre-cut fasteners with specific thread configurations—often different on each end—with one end designed for permanent installation into a tapped hole and the other end for removable assembly. Studs are commonly used in applications requiring frequent disassembly, such as engine components, flanged connections, and precision machinery.

Studs are preferable to bolts in several scenarios: when frequent disassembly is required (as they reduce thread wear in the base material), when thermal expansion differences between materials might cause binding with bolts, when space limitations make bolt head clearance problematic, and in high-vibration environments where studs provide more uniform load distribution across multiple fastening points. They're especially common in automotive engines, pressure vessels, and heavy machinery applications.

For proper installation of threaded studs, first identify the correct end for permanent installation (usually the shorter threaded portion). Use a stud driver or double-nut method to install the stud to the recommended depth or torque. For the double-nut method, thread two nuts onto the installation end, tighten them against each other, then use a wrench on the outer nut to drive the stud. Once installed, remove the nuts and attach your component using a washer and nut on the exposed end. For precise applications, follow manufacturer torque specifications.
