This displacement-controlled expansion anchor features improved geometry in the preassembled expansion plug, enabling installation with up to 40% fewer hammer strikes than previous versions — reducing installer fatigue and speeding up the job. Once properly set using the Simpson Strong-Tie DIABST50 hand setting tool or DIABST50-SDS power setting tool (sold separately), the anchor is ready to accept 1\/2\"-13 UNC threaded rod or bolts. A positive-set marking indicator at the top of the anchor gives installers a clear visual confirmation that the anchor is fully and properly installed — eliminating guesswork and ensuring consistent load capacity. Zinc-plated carbon steel construction provides corrosion resistance for dry interior applications. Widely used for MEP pipe hangers, conduit supports, cable trays, suspended lighting, HVAC equipment, and general overhead concrete fastening.
