Our Galvanized Carbon Steel Drop-in Anchors are high-performance fastening solutions engineered for heavy-duty structural applications. Manufactured from premium carbon steel (Grades 4.8 to 12.9), these anchors provide exceptional load-bearing capacity and stability in concrete substrates, ensuring secure connections for structural steel, metal buildings, and industrial machinery.
Designed for versatility and durability, these anchors are available in various knurling options—including no knurling, half knurling, and double knurling—to meet specific installation requirements. With a wide range of protective finishes such as Hot Dip Galvanized (H.D.G) and Zinc Plating, they offer superior corrosion resistance for demanding environments in the oil, gas, and wind energy sectors.

Frequently Asked Questions
Knurling prevents the anchor from rotating during installation. Half knurling provides basic grip, while double knurling offers maximum resistance against rotation in softer concrete.
For high-salinity or humid outdoor environments, we strongly recommend the Hot Dip Galvanized (H.D.G) finish, as it provides the thickest and most durable protective layer against corrosion.
The drill bit size must match the outer diameter of the anchor. For example, an M10 anchor requires a 10mm bit, while a 1/2" anchor requires a 5/8" bit as per our specification table.
Yes, with carbon steel grades up to 12.9, our anchors are specifically designed for mechanical machines, structural steel, and heavy-duty industrial equipment.
Absolutely. We offer comprehensive OEM services and can manufacture anchors to non-standard specifications and custom marks based on your technical drawings.
We provide ISO9001, CE, SGS, and BV certifications to ensure that our fasteners meet international safety and quality standards for construction and manufacturing.
