Threaded Rods
All Threaded Rods – Standards, Grades, Materials, and Finishes
Versatile Fastening Solutions for Structural, Mechanical, and Industrial Applications
All threaded rods, also known as studs or fully threaded bars, are essential fastening components used in a wide range of applications, including construction, steel fabrication, concrete anchoring, equipment assembly, and infrastructure development. With full-length threading, they offer maximum flexibility in tensioning, bracing, and joining systems.
Common Specifications and Standards
All thread rods are manufactured to meet several international and ASTM standards:
-
ASTM A307 – Low carbon steel, general-purpose applications
-
ASTM A193 (Grades B7, B8, B8M) – High-strength alloy and stainless steel for high-pressure, high-temperature use
-
ASTM F1554 (Grades 36, 55, 105) – Anchor rods for concrete embedment, available in weldable and high-strength options
-
ASTM F593 – Stainless steel rods for corrosion-resistant applications
-
DIN 975 – Metric all thread rods, typically available in Classes 4.6, 8.8, and 10.9
Material Options
Threaded rods come in a variety of materials to suit environmental and mechanical requirements:
-
Low carbon steel – Cost-effective and easy to fabricate (A307, F1554-36)
-
Alloy steel – High strength and heat resistance (A193 B7, F1554-105)
-
Stainless steel (304/A2, 316/A4) – Excellent corrosion resistance (F593, DIN 975)
Available Finishes
Different coatings are available to match environmental exposure and design needs:
-
✅ Plain finish – Ideal for dry, indoor use or post-fabrication coatings
-
✅ Clear Cr3 zinc plating – Moderate corrosion resistance with a clean look
-
✅ Hot-dipped galvanized (HDG) – Heavy-duty rust protection for outdoor and embedded applications
All Thread Rods Tailored for Any Jobsite or Application
With a wide selection of specifications, grades, materials, and finishes, all thread rods provide the strength and adaptability required for today’s toughest fastening challenges.
