The Simpson HDIASTS25 1/4" Solid Material Setting Tool for Hollow Drop-In Anchor is a purpose-built instrument from Simpson designed to properly drive and expand Hollow Drop-In Internally Threaded Anchors within drilled holes in solid base materials. By delivering the force needed to fully seat and lock the anchor before any threaded rod or fastener is installed, this setting tool helps ensure a secure, reliable connection in brick, normal-weight concrete, and lightweight concrete - making it an essential component for overhead and suspended fastening applications.

Key Features

• Engineered specifically for 1/4" Hollow Drop-In anchors - purpose-matched geometry ensures the anchor is driven to the correct depth and fully expanded, eliminating guesswork during installation.
• Compatible with solid base materials including brick, normal-weight concrete, and lightweight concrete - gives contractors confidence across a wide range of common construction substrates without needing multiple tools.
• Properly expands and locks the anchor within the drilled hole - a correctly set anchor supports the performance demands of threaded rod suspension systems, overhead cable tray hangers, HVAC ductwork, and fire sprinkler installations.
• Designed for use with HDIA25 and HDIA25SS anchor models - direct compatibility with both standard and stainless steel variants of the 1/4" Hollow Drop-In Internally Threaded Anchor keeps your installation system consistent and straightforward.

Why This Product

• A matched tool for a matched anchor - using a setting tool sized and designed for the specific anchor model means the anchor expands correctly every time, reducing the risk of an improperly set fastener in critical overhead applications.
• Supports a broad range of commercial and mechanical installations - from suspending electrical cable trays and HVAC ductwork to anchoring fire sprinkler pipe and sprinkler heads, this tool addresses the real-world demands of multi-trade overhead work in solid concrete and brick structures.
• Simplifies two-anchor compatibility in one tool - a single setting tool handles both the standard HDIA25 and the stainless steel HDIA25SS, reducing the number of specialty tools needed on the job site.
• Built to complement a proven anchor system - as a Simpson accessory matched to Simpson Hollow Drop-In anchors, this setting tool integrates directly into an established fastening solution trusted for internally threaded rod suspension in solid material overhead applications.

Frequently Asked Questions

Which anchor models is the HDIASTS25 compatible with?

The HDIASTS25 setting tool is designed for use with Hollow Drop-In models HDIA25 and HDIA25SS, both of which are 1/4" internally threaded anchors.

What base materials can this setting tool be used with?

This tool is designed for use in solid materials, including brick, normal-weight concrete, and lightweight concrete.

What is the primary purpose of a setting tool for drop-in anchors?

The setting tool is used to properly drive and expand the Hollow Drop-In Internally Threaded Anchor within the drilled hole, strongly reinforcing it so it is securely locked into the solid base material before a threaded rod or fastener is installed.

What types of installations commonly use the HDIASTS25?

This setting tool is commonly used in applications where threaded rod must be suspended from solid overhead materials, such as for hanging electrical cable trays, HVAC ductwork, and fire sprinkler pipe and heads.
