Thread Rod
Qi Sheng supplies industrial threaded rods for OEM manufacturers, distributors, and project-based buyers. Thread rods are widely used for anchoring, bracing, hanging systems, and general fastening where adjustable length and strong clamping force are required. Our range includes full thread rods for general connections and stud bolts for flanged joints and engineered assemblies.
We support specification-based sourcing by thread standard (metric/imperial), diameter and length, material and strength grade, and surface finishes for corrosion protection. If you are matching existing hardware or a BOM, we can help confirm thread requirements and recommend suitable options for your application.
For fast quoting, please share: product type, thread size, length, material/grade, finish, quantity, and delivery destination.
