The Simpson Anchor Bolt Locator for 7/8" Bolt with OST Nut is a precision concrete-forming component engineered by Simpson to enable accurate and secure placement of anchor bolts on concrete-deck forms prior to concrete placement. The structural heavy-hex nut is attached directly to a pre-formed steel chair, eliminating the need for an additional nut on the bottom of the anchor bolt and simplifying the overall installation process. Designed specifically for use with hot-dip galvanized anchor bolts, this locator delivers consistent bolt positioning and reliable performance in demanding concrete forming applications.

Key Features

• Structural heavy-hex nut attached to a pre-formed steel chair - eliminates the need for a separate bottom nut, reducing hardware requirements and speeding up installation on the form
• Electrogalvanized nut finish - ensures compatibility with hot-dip galvanized anchor bolts, making this OST version the correct choice when HDG hardware is specified
• 14-gauge steel chair with G90 finish - provides a sturdy, corrosion-resistant base that holds anchor bolts firmly in position throughout the concrete pour
• 1" stand height - positions each 7/8" diameter anchor bolt at a consistent, repeatable elevation on the concrete-deck form, supporting accurate bolt placement every time
• Designed for concrete-deck forming applications - keeps anchor bolts properly located before and during concrete placement, reducing the risk of misalignment and costly corrections after the pour

Why This Product

• Simplified installation with fewer components - because the heavy-hex nut is pre-attached to the chair, contractors eliminate one piece of hardware per bolt location, reducing setup time and the chance of missing parts on the form
• Built for HDG anchor bolt compatibility - the electrogalvanized OST nut finish is specifically selected to work with hot-dip galvanized bolts, so contractors working on galvanized assemblies get a locator engineered to match their hardware
• Consistent, repeatable bolt positioning - the fixed 1" stand height and pre-formed steel chair hold each 7/8" anchor bolt at the same elevation across the entire form, supporting precise, uniform results from pour to pour
• Domestic quality from a trusted structural brand - engineered by Simpson, a recognized name in structural connectors and concrete forming hardware, this anchor bolt locator is built to perform in professional concrete construction settings

Does this anchor bolt locator eliminate the need for an extra nut?

Yes. The structural heavy-hex nut is attached directly to the pre-formed steel "chair," which eliminates the need for an additional nut on the bottom of the anchor bolt during installation.

What is the stand height of the ABL7-1-OST?

The ABL7-1-OST features a 1" high stand, which positions the anchor bolt at a consistent elevation on the concrete-deck form prior to concrete placement.

What materials and finishes are used in the construction of this anchor bolt locator?

The nut is a heavy-hex type with an electrogalvanized finish, while the chair is constructed from 14-gauge steel with a G90 finish, providing reliable performance in concrete forming applications.
