Product Overview This product is a fully threaded stud bolt / threaded rod manufactured from high-strength carbon steel with a zinc-plated finish. Also known as an all-thread rod, threaded bar, or studding, it features a continuous external thread along its entire length with no head, enabling versatile fastening, anchoring, and support applications. The zinc plating provides reliable corrosion resistance for general industrial, construction, and outdoor use. The product is available in metric sizes from M6 to M64 and in multiple strength grades including 4.8, 8.8, 10.9, and 12.9, meeting the requirements of DIN 975, DIN 976, GB/T 897–900, and other international standards. Product Type & Design Feature Description Product Type Fully Threaded Stud Bolt / Threaded Rod / All-Thread Rod Head Type Headless (no head) Thread Configuration Full thread along entire length Thread Direction Right-hand (left-hand available on request) The headless, fully threaded design offers several advantages: it saves installation space, allows nuts to be locked at any position along the rod, and enables symmetrical fastening from both ends for uniform load distribution. This makes it particularly suitable for through-bolting, anchoring, and use as a support rod in compact or recessed installations. Material & Strength Grades Grade Material Tensile Strength (min.) Yield Strength (min.) Typical Applications 4.8 Low carbon steel (Q235) 400 MPa 320 MPa General fastening, light structural 8.8 Medium carbon steel (45#) 800 MPa 640 MPa Structural connections, machinery 10.9 Alloy steel (35CrMo/40Cr) 1,040 MPa 940 MPa High-strength structural, heavy machinery 12.9 Alloy steel 1,220 MPa 1,100 MPa Critical high-strength applications For comparison, DIN 975 Class 4.6 low carbon steel threaded rod achieves approximately 58,000 psi (400 MPa) tensile strength with 34,000 psi (235 MPa) yield strength and a hardness of approximately Rockwell B95. ASTM A307 Grade A threaded rod (low carbon steel) has a minimum tensile strength of 60,000 psi (414 MPa) and typical hardness of HRB 70–100. Surface Finish Options Finish Coating Thickness Salt Spray Resistance Recommended Environment Zinc Plated (Blue-White) 8–12 μm 72–144 hours Indoor, general industrial Zinc Plated (Yellow) 8–12 μm 96–168 hours Outdoor, moderate corrosion Hot-Dip Galvanized (HDG) 45–85 μm 500–800 hours Outdoor, marine, heavy corrosion Black Oxide 1–2 μm 24–48 hours Indoor, tooling, machinery Dacromet 8–10 μm 500+ hours Automotive, high-corrosion Plain — 24–48 hours Temporary, indoor The zinc plating on this product provides sacrificial protection to the underlying carbon steel — the zinc coating corrodes preferentially, protecting the steel substrate from rust. For more aggressive environments, hot-dip galvanizing (HDG) to ASTM A153 is recommended, providing substantially thicker coating and longer service life. Applications Carbon steel zinc-plated threaded rods are widely used in: Construction & structural steel — Column base anchoring, bracing, tie rods, formwork Industrial machinery — Equipment assembly, frame connections, adjustment rods Petrochemical & piping — Flange bolting, valve connections, pipe supports Electrical & HVAC — Hanging and mounting conduit, cable trays, ductwork supports Automotive & transportation — Component fastening, exhaust systems General fabrication — Cutting to length for on-site use as studding or tie bars The zinc-plated finish makes these rods suitable for both indoor and outdoor applications where moderate corrosion resistance is required. For coastal, marine, or chemically aggressive environments, hot-dip galvanized or stainless steel alternatives are recommended.
