The Simpson DIAST37P1 Setting Tool for 3/8-in. Rod DIA Drop-In Anchor is engineered by Simpson to properly and consistently install Simpson Strong-Tie Drop-In internally threaded anchors in concrete and masonry applications. Drop-ins are set by driving the expander plug toward the bottom of the anchor until the shoulder of the setting tool makes contact with the top of the anchor, delivering a reliable, repeatable installation every time. Using a fixed-depth drill bit in tandem with this tool prevents overdrilling, saving time on the job and prolonging bit life.

Key Features

• Dedicated setting tool for DIA anchors - purpose-built to deliver consistent, properly set drop-in anchors rather than relying on improvised methods that risk poor installation.
• Compatible with Simpson Strong-Tie Drop-In models DIA37SS and DIA376SS - ensures a confirmed fit with the correct anchor models, eliminating guesswork and compatibility concerns on the job site.
• Sets drop-in anchors for overhead applications - specifically designed to handle the demands of ceiling and overhead anchor installation where precision and secure setting are critical.
• Made from carbon steel - provides the strength and durability needed to drive the expander plug repeatedly through demanding concrete anchor installations.
• Fixed-depth setting action - the shoulder of the tool contacts the top of the anchor to signal correct depth, preventing overdriving and protecting anchor performance.
• Drop-in anchors sold separately - allows buyers to select only the setting tool they need without paying for hardware they may already have on hand.
• Caution: Oversized holes will make it difficult to set the anchor and will reduce the anchor's load capacity - using the correctly sized drill bit is essential to achieving rated performance from the installed anchor.

Why This Product

• Consistent, professional-grade installation every time - the tool's shoulder-contact stop mechanism takes the guesswork out of anchor depth, producing properly set drop-in anchors that meet installation standards across every hole on the job.
• Protects your drill bits and saves time - pairing this setting tool with a fixed-depth drill bit actively prevents overdrilling, extending bit life and reducing time spent on each anchor installation.
• Confirmed compatibility with Simpson Strong-Tie overhead anchor systems - designed specifically for DIA37SS and DIA376SS anchors and built to handle overhead concrete fastening applications where a secure, fully expanded anchor is non-negotiable.
• Durable carbon steel construction for repetitive use - built from carbon steel to withstand the repeated impact forces of driving expander plugs, making it a reliable tool for contractors installing multiple anchors across larger projects.
