Simpson Strong-Tie's 3/8 in. x 1-9/16 in. Drop-In (DIASS) Stainless-Steel Internally-Threaded Anchor is particularly useful where a corrosion-resistant fastening point is needed and the connected component may require removal or replacement. Installation involves drilling an appropriately sized hole, placing the anchor into the substrate, and setting it with the specified setting tool so the internal expansion mechanism engages correctly. Stainless-steel construction helps the anchor withstand corrosive conditions better than standard carbon-steel alternatives, making it appropriate for many indoor and outdoor concrete fastening projects. The 100-pack provides a practical quantity for contractors handling repeated anchoring installations.
