The Simpson DIABST37-SDS SDS-plus Power-Setting Tool by Simpson is purpose-built for the proper and consistent installation of internally threaded drop-in anchors in concrete. Designed specifically for use with Simpson Drop-In models DIAB37 and DIABL37, this carbon steel setting tool works by driving the expander plug toward the bottom of the anchor until the shoulder of the tool makes contact with the top of the anchor - delivering a fully seated, reliably set anchor every time. Its SDS-plus shank makes it compatible with power rotary hammer tools, and it is engineered to handle both standard and overhead concrete anchor installations.

Key Features

• SDS-plus shank power setting tool - connects directly to SDS-plus rotary hammers, allowing faster and more consistent anchor setting compared to manual methods
• Compatible with DIAB37 and DIABL37 drop-in anchors - designed exclusively for these Simpson 3/8 in. rod drop-in anchor models, ensuring a precise fit and correct installation every time
• Rated for overhead applications - engineered to set drop-in anchors in ceiling and elevated concrete installations, expanding the range of job conditions you can work in confidently
• Carbon steel construction - provides the durability and strength needed to withstand repeated power-tool-driven anchor setting on the job site
• Shoulder-contact setting mechanism - installation is complete when the tool shoulder contacts the top of the anchor, giving you a clear, built-in indicator that the anchor is fully and consistently set
• Caution - oversized holes will make it difficult to set the anchor and will reduce the anchor's load capacity - always drill to the exact specified diameter to protect installation integrity and maintain full load performance

Why This Product

• Consistent, repeatable anchor setting - the shoulder-stop design takes the guesswork out of installation by providing a definitive physical indicator that each drop-in anchor is fully driven and properly expanded, reducing the risk of under-set anchors on every pour
• Built for power tools - the SDS-plus shank integrates with standard rotary hammer drills, letting crews set anchors faster and with greater force than manual setting tools allow
• Overhead-capable design - unlike general-purpose setting tools, this tool is specifically engineered to handle the added challenge of ceiling and elevated concrete anchor installations, making it a practical choice for mechanical, electrical, and structural overhead work
• Exact-fit compatibility with Simpson Drop-In anchors - purpose-matched to DIAB37 and DIABL37 anchor models, this tool works as part of a complete Simpson system, helping ensure anchor performance meets the specifications those anchors were rated for

How does this setting tool work to install a drop-in anchor?

The setting tool drives the expander plug toward the bottom of the anchor. Installation is complete when the shoulder of the setting tool makes contact with the top of the anchor, ensuring the anchor is fully and consistently set.

Can this tool be used for overhead anchor installations?

Yes. The DIABST37-SDS is specifically designed to set drop-in anchors in overhead applications, making it suitable for ceiling and elevated concrete installations.

What happens if the drilled hole is too large for the anchor?

Oversized holes will make it difficult to set the anchor and will reduce the anchor's load capacity. Always drill to the exact specified diameter to ensure proper installation and full load performance.
