L H Dottie Co DA50 Drop in Anchor 1/2-13 50 Pc

Product Description

The L H Dottie Co DA50 is a 1/2-13 drop-in anchor sold in a 50-piece set. Drop-in anchors are internally threaded fasteners designed for use in solid concrete and masonry substrates. They are set by driving an expansion plug into the anchor body with a setting tool, causing the lower end to flare outward and lock the anchor in place. The 1/2-13 thread designation indicates a 1/2-inch nominal diameter with 13 threads per inch, a common size for structural and mechanical attachment in commercial and industrial construction.

Drop-in anchors at this thread size are widely used by electricians, plumbers, HVAC installers, and general contractors for anchoring threaded rod, conduit supports, pipe hangers, equipment mounts, and unistrut channel to concrete ceilings, walls, and floors. The 50-piece pack quantity is suited to multi-point installations and job-site stocking where consistent fastener size is required across multiple anchor points.

Installation Notes

Installation requires drilling a correctly sized hole in cured concrete using a hammer drill and carbide-tipped bit sized to the anchor manufacturer specification. A proper setting tool must be used to expand the anchor — do not substitute a punch or improper driver. Follow applicable building codes and engineered load ratings when using drop-in anchors for structural or overhead suspension applications. Always wear appropriate eye and hand protection when drilling and setting concrete anchors.
