The Simpson DIABST50 Setting Tool is purpose-built for properly and consistently installing Simpson Drop-In internally threaded anchors into concrete and masonry. 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, this tool delivers a reliable, repeatable set on every installation - including demanding overhead anchor applications.

Key Features

• Dedicated setting tool for DIAB anchors - engineered specifically for Simpson Drop-In anchor models, so you get a correctly seated anchor every time rather than risking an improperly set fastener.
• Compatible with DIAB50, DIABL50, and DIAB50C - covers the full range of Simpson 1/2 in. Drop-In anchor variants, giving you one tool that works across multiple project configurations.
• Designed for overhead installation - built to handle the added challenge of setting drop-in anchors in overhead positions, expanding the range of applications where you can confidently use these anchors.
• Carbon steel construction - provides the hardness and durability needed to drive the expander plug consistently under repeated use on the job site.
• Shoulder-stop design - the shoulder of the tool contacts the top of the anchor at full set, giving you a clear, tactile signal that installation is complete and eliminating guesswork.
• Hole size caution built into proper use - using the correct drill diameter is critical, as oversized holes make it difficult to set the anchor and reduce load capacity, so this tool works best as part of a careful, spec-compliant installation process.

Why This Product

• Consistent, repeatable anchor installation - the shoulder-stop mechanism removes the uncertainty of hand-setting, ensuring every Drop-In anchor is driven to the correct depth for full load-bearing performance.
• Broad anchor compatibility in one tool - a single DIABST50 handles multiple Simpson 1/2 in. Drop-In anchor models, reducing the number of specialty tools you need to keep on hand for concrete anchoring work.
• Built for real job-site conditions - carbon steel construction and a design cleared for overhead applications mean this setting tool holds up to the repetitive impact and varied positioning demands of professional concrete anchor installation.
• Simpson-matched precision - using a manufacturer-matched setting tool with Simpson Drop-In anchors helps preserve the anchor's rated load capacity, protecting the integrity of the connection where it matters most.
