The Simpson ABL6-1-OST Anchor Bolt Locator is a precision-engineered positioning tool designed to hold 3/4 in. diameter anchor bolts accurately and securely on concrete-deck forms prior to concrete placement. Built by Simpson, this anchor bolt stand features a structural heavy-hex nut with an electrogalvanized (OST) finish attached to a pre-formed steel chair, streamlining the concrete forming process for HDG anchor bolt applications.

Key Features

• Electrogalvanized OST heavy-hex nut - specifically compatible with HDG anchor bolt applications, ensuring a reliable galvanic match and reducing the risk of corrosion-related incompatibility on the jobsite.
• Nut attached directly to the pre-formed steel chair - eliminates the need for a separate nut on the bottom of the anchor bolt, saving installation steps and reducing the chance of misalignment or missing hardware.
• 1 in. stand height positions 3/4 in. anchor bolts at correct elevation - ensures bolts are set at the proper depth within the form, promoting consistent, code-conscious concrete placements without guesswork.
• 14-gauge steel chair with G90 finish - delivers structural rigidity and corrosion resistance during the forming process, holding bolt position firmly while concrete is poured and consolidated around it.
• Designed for concrete-deck forming applications - purpose-built geometry keeps anchor bolts stable and accurately located on the form deck, reducing post-pour corrections and rework.

Why This Product

• Simplified installation with fewer components - because the heavy-hex nut is pre-attached to the chair, contractors eliminate one hardware component per bolt location, speeding up form setup and reducing the chance of an underslung nut being omitted.
• Built for HDG anchor bolt compatibility - the electrogalvanized OST nut finish is intentionally matched for use with hot-dip galvanized anchor bolts, making this the correct choice for projects specifying HDG hardware rather than a generic stand that may cause galvanic concerns.
• Consistent bolt placement every time - the fixed 1 in. chair height and rigid 14-gauge steel construction hold each 3/4 in. anchor bolt at a repeatable, accurate elevation on the form, supporting quality control across multiple pours.
• American-made quality from a trusted structural brand - produced in the United States by Simpson, a brand with a long track record in structural connectors and concrete accessories, giving specifiers and installers confidence in dimensional accuracy and material consistency.

Frequently Asked Questions

What type of anchor bolts is the ABL6-1-OST designed for use with?

The ABL6-1-OST is specifically designed for use with HDG (hot-dip galvanized) anchor bolts. The electrogalvanized OST nut finish ensures compatibility with HDG anchor bolt applications.

What is the purpose of the pre-formed steel chair on the ABL6-1-OST?

The structural heavy-hex nut is attached to a pre-formed steel chair, which eliminates the need for an additional nut on the bottom of the anchor bolt. This simplifies installation and ensures accurate positioning on concrete-deck forms prior to concrete placement.

What are the material and finish specifications for the ABL6-1-OST?

The nut is made from heavy hex material with an electrogalvanized finish, while the chair is constructed from 14-gauge steel with a G90 finish, providing strength and corrosion resistance suitable for concrete forming applications.

How tall is the ABL6-1-OST anchor bolt stand?

The ABL6-1-OST anchor bolt stand has a height of 1 inch, designed to position 3/4-inch diameter anchor bolts at the correct elevation on concrete-deck forms prior to concrete placement.
