Threaded Rods

Threaded rods, also known as all-thread, studding, or fully threaded bars, provide reliable tensioning, fastening, and hanging across construction, HVAC, electrical, plumbing, woodworking, and automotive projects. Available in common standards like metric (M6–M24 and beyond) and imperial UNC/UNF (from 6-32 to 1 in.), these rods are easy to cut to length and connect with coupling nuts for extended runs. Pair with flat washers, lock washers, hex nuts, beam clamps, rod hangers, and strut channel hardware to build strong assemblies, suspend ductwork and pipe, anchor machinery, or create adjustable jigs and fixtures.

Choose material to match strength and environment. Low-carbon steel (A36/A307) suits general indoor use. Zinc-plated steel offers basic corrosion protection. Hot-dip galvanized rods improve outdoor and concrete-embed durability. For aggressive environments, 304 stainless steel balances corrosion resistance and cost, while 316 stainless steel adds superior resistance in marine and chemical exposure. For high temperature or high load applications, alloy grades such as ASTM A193 B7 are common. Coarse threads (UNC/metric coarse) speed assembly and resist cross-threading; fine threads increase holding power and allow more precise preload.

Installation is straightforward: cut with a hacksaw or cutoff wheel, then chamfer the cut end so nuts start smoothly. Verify thread compatibility (pitch and diameter), use two-nut locking or nylon-insert lock nuts to resist vibration, and apply thread locker where needed. For anchoring into concrete or masonry, pair nuts and washers with wedge anchors, drop-in anchors, or epoxy systems sized to the rod. Always consult load tables and local codes, especially for overhead supports.

Benefits include broad size availability, easy customization, and strong, continuous clamping force over long spans. Whether you need to buy short lengths for a one-off repair or bulk threaded rod for routine MEP installations, you’ll find options in steel, stainless, and galvanized finishes, along with the right accessories to build safe, code-compliant connections.
