AB6212HDG 5/8" x 12" Hot Dip Galvanized Anchor Bolt — Long-Term Corrosion Resistance for Structural Anchorage

The AB6212HDG is a 5/8" diameter by 12" long hot dip galvanized anchor bolt engineered by OCM Inc. for professional use in commercial, industrial, and residential construction applications. The hot dip galvanized coating provides a thick, high-resistance barrier against corrosion and rust, making this bolt well suited for moist environments and exterior installations. Primary use cases include base plate anchorage and sill plate anchorage to freshly poured concrete. These bolts comply with ASTM A307 and ASTM A153, Class C industry standards.

Technical Specifications

Available Sizes — OCM Anchor Bolt Product Line

The hot dip galvanized finish on the AB6212HDG delivers a thicker, more durable protective coating compared to electroplated alternatives, making it the appropriate choice for exterior and moisture-exposed installations. Its approval for use with all types of treated lumber sets it apart for sill plate applications where ACQ or other treated wood is specified. Compliance with both ASTM A307 and ASTM A153, Class C ensures the bolt meets recognized industry structural and coating standards.

Key Features & Benefits

Hot Dip Galvanized Coating

The hot dip galvanizing process coats the steel with a thick layer of zinc, providing high resistance against corrosion and rust. This makes the AB6212HDG suitable for moist environments and exterior applications where plain steel bolts would degrade prematurely, reducing long-term maintenance costs and ensuring structural integrity over the service life of the installation.

Approved for Use with All Types of Treated Lumber

OCM anchor bolts are approved for exterior use with all types of treated lumber, including chemically treated wood products. This approval is critical for sill plate anchorage applications where treated lumber is required by code, ensuring compatibility and eliminating the risk of accelerated corrosion from chemical interaction.

Excellent Holding Power and Stability

These anchor bolts are engineered to provide excellent holding power and stability when set in freshly poured concrete. Reliable embedment strength is essential for base plate and sill plate connections that must resist lateral and uplift forces in structural applications.

ASTM A307 and ASTM A153, Class C Compliance

Compliance with ASTM A307 (carbon steel bolts) and ASTM A153, Class C (zinc coating by hot dip process) confirms that both the mechanical properties of the fastener and the quality of the galvanized coating meet established industry standards. This simplifies specification and inspection on commercial and industrial projects.

Broad Size Range Available

The OCM anchor bolt line spans 1/2", 5/8", and 3/4" diameters in multiple lengths, available in both plain and hot dip galvanized finishes. Contractors can source multiple sizes from a single supplier, streamlining procurement across different project requirements.

Common Applications

Base Plate Anchorage

The AB6212HDG is designed for anchoring structural steel base plates to freshly poured concrete foundations, providing the embedment depth and holding power required for column and post connections.

Sill Plate Anchorage

Used to anchor wood sill plates to concrete foundations, the hot dip galvanized finish ensures compatibility with treated lumber and resistance to moisture at the foundation-to-framing interface.

Moist and Exterior Environments

The galvanized coating makes this bolt appropriate for installations exposed to moisture, humidity, or outdoor conditions where corrosion resistance is a primary requirement.

Commercial and Industrial Construction

Engineered for professional use, the AB6212HDG is suited for commercial and industrial projects where fastener performance, dimensional consistency, and standards compliance are specified.

Residential Construction

Suitable for residential foundation anchorage applications, including sill plate attachment in new construction where treated lumber and exterior exposure are standard conditions.

Compatible Materials

• Freshly poured concrete (cast-in-place embedment)
• All types of treated lumber (ACQ and other chemical treatments)
• Structural steel base plates
• Wood sill plates

Frequently Asked Questions

Q: What standards does the AB6212HDG comply with?
A: The AB6212HDG complies with ASTM A307 (carbon steel bolts) and ASTM A153, Class C (hot dip zinc coating), confirming both the mechanical and coating properties meet recognized industry standards.

Q: Is this anchor bolt approved for use with treated lumber?
A: Yes. OCM anchor bolts are approved for exterior use with all types of treated lumber, making them suitable for sill plate anchorage applications where chemically treated wood is specified.

Q: How is this bolt installed?
A: The AB6212HDG is designed to be cast in place — embedded into freshly poured concrete before it sets. It is not intended for post-installed or drilled-in applications.

Q: Why choose hot dip galvanized over plain steel for this application?
A: Hot dip galvanizing coats the steel with a thick zinc layer that provides high resistance against corrosion and rust, making it the appropriate choice for moist environments, exterior use, and installations involving treated lumber where plain steel would be susceptible to accelerated corrosion.

Q: Are other sizes and finishes available in the OCM anchor bolt line?
A: Yes. OCM offers anchor bolts in 1/2", 5/8", and 3/4" diameters, in lengths ranging from 6" to 24", available in both plain and hot dip galvanized finishes. See the Available Sizes table above for the full product matrix.
