Threaded Rods

Anchor, connect, or hang components in a wide variety of applications, from mounting I-beams to suspending light fixtures.

Stainless Steel

More corrosion resistant than steel rods and comparable in strength to low-strength steel.

Ultra-Corrosion-Resistant Alloy 20 Stainless Steel—The most corrosion-resistant stainless steel rods we offer, these hold up in just about any environment. They won't pit or weaken when exposed to salt water and harsh chemicals, such as sulfuric acid. They’re often used in chemical-processing, battery-production, and metal-finishing equipment. Also known as Carpenter 20.
